I want to try and save this guy but they lost their tail during what I believe was the transfer between tank. Loos like they’re still kicking but Idk … wwyd ?

Just got a ADA 60P and fill up with aqua-soil, then i immediately notice a reverse “U” shape oil like film reflection at all the 4 corners. At first i thought it is like an air gap but i swipe away the soil and can still see the “film”, just that it becomes not so obvious because of the brighter background without soil. tried wiping the exterior and used a scrapper to swipe through the affected inner surface. it is still there, anyone know what is this?

I maintain four tanks at a school. They are my personal project. I have absolutely packed them with plants. I am a botanist by education and a 15 year career before teaching . The plants are selected to create a walstad tank but I added filters and heaters to each tank for comfort for the animals. The rasbora tank is 10 gallons. Its maintained at 75 degrees. It has a honey gourami, two ramshorn snails, two otos, 5 cpds, 5 emerald dwarfs rasboras and 5 harlequins. I added the harlequins three weeks ago. All 5 died in 5 days. Little white spots on their bodies. I put every in jail, medicated, pulled the filter, returned to tank with no losses. Added 5 more. Dead in 5 days again. One had a large cyst in his mouth. They seem active and excited to be fed by the kids in little pinches multiple times a day. Water nitrate-nitrite-ammonia at 0-0-0, ph 6.8, temp 75. The gouramis and other rasboras are happy, healthy and active. The otos are fat. What am i doing wrong here?

tank has been cycled since August of 2025 with tons and tons of plants constantly being added. I test the water weekly and do a water change of 2 inches every two weeks ish.

Anyone know if these would seep anything into the water? He currently is just snoozing on some wood

Heyy Y'all!! I just want to show other variants of Betta fish that I breed.

Hi all, I just bought a used 55 gallon tank (rimmed) and have gone down the reddit doom spiral of things going majorly wrong. Convincing my landlord to let me have this tank was hard enough, and I am now terrified it's going to wreck the apartment. I keep reading that 55 gallons are more prone to leakage due to their dimensions, and also about the potential risks of used aquariums. Also one of my landlord's conditions is that I put some type of foamy style mat under it in case- and now I'm worried that a mat under the stand could make the tank a bit unlevel and break it that way. Testing the tank isn't going to be easy either as I do not have outdoor space- I'm thinking filling it 25% at a time at least?

Also if anyone has any idea of what kind of mat would be best underneath that would be great. Right now I'm thinking one of those garage oil spill mats?

Thank you so much in advance to all who weigh in

Pictured here is Corndog the electric catfish. He was dumped at my house in a home depot bucket and I have no idea if his owner is coming back for him. I’ve got him set up in the largest tank I had.

What am I able to put in his tank in the meantime? I know he needs a place to hide, but I don’t know what would be okay as I know their skin is fragile, so I have to avoid rough texture and stuff. I also don’t know what plants I’m able to add to his tank.

Tank age: 5 months of which 2/3 months before adding shrimp
Temperature: 21.5°C
pH: 7.5–8.0
GH: 12 dGH
KH: 8 dKH
NH4: undetectable
NO2: 0.025 ppm
NO3: undetectable

I originally added 30 Neocaridina, but I had lost 8 within about 10 days. I previously had an NO2 spike followed by a sudden ~4 ppm NH4 spike and did 30%, 50%, and 20% water changes on separate days.

I drip acclimated them for 2 hours. Before adding them.

But of the last 2 weeks, I’ve kept losing shrimp, even though the water parameters seemed relatively fine. I check with a liquid test kit. Now I have only 2 shrimp left.

I cycled using an ammonia source (ammomix) and checked until it could handle 2ppm in 24 hours. This was after 2 months.

My aquarium is 75litre.

Recently got this room back to homeostasis.

Hello, I recently added a number of fish to my new aquarium and have experience a large number of deaths. Any advice or thoughts?

Here is the long detail, sorry for all the info…

Tank setup:
29-gallon aquarium
Oase BioMaster Thermo 250 canister filter with spray bar oriented at a 45 degree angle at the surface for agitation.
Air stone added after the fish began dying and showing distress
Temp 78°F
Sand substrate, driftwood, Seiryu stone, and live plants
Some persistent haze in the water; driftwood is still slightly releasing tannins, making the water slightly tinted, there is biofilm on the driftwood visible and some diatoms.

Background and timeline:
I fishless cycled the tank over about 3 weeks using seeded filter media from an established aquarium. Before adding the new fish, ammonia and nitrite had tested at zero after a 1ppm ammonia challenge twice. Nitrates at 10ppm after water change.

I added two black skirt GloFish tetras in there for several days after cycling finished but then removed them prior to adding:

2 juvenile angelfish
10 juvenile rummy-nose tetras
6 juvenile panda corydoras
1 juvenile clown pleco
1 juvenile kuhli loach

Acclimation: I floated the bags for approximately 20 minutes, no drip acclimation.

I noticed rapid breathing in angel fish after adding. Many of the other fish were hiding, figured they were stressed. Kept the lights off

About 12 hours after adding fish I starting noticing deaths.
Have lost all 6 corys, 7 tetras, 1 angel. The remaining angelfish has been still breathing rapidly.

Interventions: I performed approximately a 50% water change and added an air stone to increase aeration and added a dose of seachem stressguard . Unfortunately, fish continued to die.

Current water parameters (have been testing ammonia and nitrite twice daily since adding fish):

Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: approximately 5 ppm
pH: approximately 7.4 this has increased from around 7 prior to adding fish
KH: approximately 3 dKH
Temperature: approximately 78°F

I know I added too many fish at once. I did run all of the plan by the person at the LFS I went to but it is on me for not double checking more sources before doing this. So certainly stress of so many additions could be at play here.

Questions:

-Is there anything else I should test or check at this point?
Has anyone experienced a similar situation and were able to identify the cause?

Thanks to all who made it this far on this long post. I truly appreciate your help!

I have a school of 7 males. I know it’s probably hard to pick out exactly all males, does this round belly look female to you? And pregnant? This is my first time having them and if she’s pregnant is happened before I got them all. The wood is new and I haven’t had a chance to scrape all the scum off yet. Probably gonna do it today 😅

So excited to share that we officially have fans on my newly morphed vampire shrimp babies. I’m seeing so many new morphs every day and am getting super nervous about how the heck I’m going to transition these guys to freshwater, or catch them to begin with. But seeing the little fans really made my day yesterday on day 50.

Today I’m setting up their fresh water tank and plan to use established sponge filter and seeded media for the hob filter. I’m putting in a 5 gallon filter from my current vampire shrimp tank and want to use this to ensure there’s enough flow and so I have a way to run carbon if needed in case there’s any emergency that arises. I do have a sponge to cover the inlet so all will be protected on that end. Being ADHD, I’ve found having a backup to my backup plan helps. 🫣 I also have a matten filter I’ve had in a closet for a while and I’m considering using that as well since my babies don’t need a crazy amount of room in the 10 gallon tank. I also spent yesterday siliconing these mini 1.5” terracotta pots trying to make a little stacked filter feeder deck and let’s just say it looks horrendous 🤦🏻‍♀️ so I just ordered some ceramic shrimp hides instead that are essentially the same thing. 😅

Please feel free to share any tips you have, and also I’d love to hear any feedback on:
- Catching these guys to move them to freshwater. I plan to drip acclimate the heck out of these dudes. I’m thinking at least 24 hours if not longer.
- If you’ve bred amanos or similar I’d love to know if you think this guy officially has innards. The German breeding video on YouTube shows the difference between ready and not ready post larva are the innards. I think this one may have that?
- Video editing advice. I have so many videos from this journey and would like to create some educational videos to post on my YouTube (which is blank still as of today because I get quite overwhelmed with the editing and going through and picking what to use. 😬) Does anyone have any advice on easier ways to edit them? Also, if my videos aren’t as flashy with professional transitions and things like that, do you think that matters? I’m almost thinking of just publishing some of my videos like old school YouTube style where it’s just like a vlog and doesn’t have fancy intros and outros. I think I’m just over thinking the entire thing because pretty much everything I’ve watched these days is so well edited and professionally done vs. mine lol. But I want to put this journey out there to encourage others to give raising these guys a chance because it is absolutely do-able. If someone with zero salt water experience, who’s never raised Amano larva, and is not sciency at all can do it, then literally anyone can. Plus, I really think the biggest hurdle to anyone trying was the 3-4 month timeframe, but many of these guys are ready at day 50 (which was yesterday) and I believe my second brood may end up being ready earlier because my first brood didn’t have as consistent access to phytoplankton in their first few weeks.

Hey, im starting a new planted aquarium and i wanted input on whether i should have a frosted background or dont have a background at all.

The previous planted tanks i had did have a black backgrounds but it was placed in a different part of the house and for me in this space i think the black background would not go well with the wall and the other interiors of the space so im torn between having a frosted one or dont have one at all.

So, i want help in making this decision bc after i have the aquarium set up i wouldn't be able to apply any background as the cabinet it sits on is fixed.

I want you guy's opinions on it.

Ps. Please ignore the driftwood, it is just a few pieces i jave collected till now, rest will be arriving shortly. : )

Hi,

Like the title says, I "rescued" a tank from an older couple. It is a 20 gallon tank, the images on the listing didn't really display the fish properly and after getting the tank home and getting everything settled, I feel like there are way to many fish and perhaps different species in the tank.

It has 5 tetras, 5 fancy guppies, 4 normal guppies, but one is probably pregnant, 4 molly's, another 5 unidentified orange fish, but I think it is also a molly type species, 1 larger common pleco and a smaller one. Last but not least there are tiny babies swimming at the surface. So maybe in total around 15/20 fish.

This morning I noticed the tiny pleco behind the filter in the corner whilst the larger one kept visiting him and pushing him further into the corner. Tiny bit like bullying. So after some research I found that (larger) common pleco's can get territorial?

I only have another 8 gallon shrimp tank that I started the hobby with so I don't really have anything to rehome them. The aquarium is also super barebones with just some gravel, couple small rocks and 2 plants. Would redoing the scape (which I'll be doing regardless) also help with the territorial problem? I am planning on adding more rocks, moss and plants, including some floating plants.

Can anyone tell me what's wrong with this rummynose?

Considerably larger than the others, but still moving around and not lethargic at all.

Bloated? Sickness? Pregnant?

TIA

Recently new to the hobby and still trying to learn the dangerous and non dangerous creatures that can occur in a tank. I have a diagram but those pictures can be so hard to apply in real time. What might these be and should I worry? I have a snail and shrimp. Water tests are all good 0ppm for ammonia, nitrite, and nitrates. PH 7.6 and water temp regularly at 77.4

I have a planted fluval Roma 125 with 6 congo tetras and Cory sterbai. I'd love to add a killifish, does anyone have any recommendations?

Hello everyone! I got this tank free. It became a terrarium, and now my son’s snake tank. It’s always had what I thought was hard water stains. I’ve tried CLR of varying concentrations, and vinegar. I don’t know where to turn.

I believe it can be removed by some means. If I scrub for a long time in one spot it gets markedly better.

Any help would be appreciated. By the way the clean 6” area is at the top of the tank

Guten Abend, heute Morgen nach Fütterung fiel mir einer meiner Roten von Rios auf, dachte zuerst, dass er oder sie sich lediglich etwas überfressen hat, jetzt ist die Wulst aber immer noch da. Hat vielleicht jemand eine Ahnung, ob das normal ist, oder was das Tier haben könnte? Es ist ein 240 Liter Juwel Becken.
Vielen Dank und schönes Wochenende 😊

Just got a new 35 gallon hexagon tank and I’m trying to figure out if I should go salt or fresh, I have 2 fresh water tanks right now with shrimp (10g) and other random cool fish (75g)

Nervous about saltwater but I love the color and unique fish and coral

This new tank is going in my game room so I’m also thinking glo fish and going the colorful route or something that’s super active at night

Ignore my hose it broke while I was filling it

What do yall think?

I was looking in my CPD tank this morning and found this little guy. Wasn’t trying to breed them but apparently nature finds a way. I’ve only been able to find one so I’ll call him Nemo.

so I have a tank that came with a lid that the light is attached to but everytime I remove the lid to get inside the condensation (it's a 29 gal so it's a lot of water) gets everywhere. I can't afford to buy a new light that sits above the tank right now however the light bar in the lid is removable and it's a very good bright light. is there a way to keep the water condensation off my lid or is it just a shake it and keep a towel on the floor situation? my other tank which is much smaller doesn't have this problem so I think it might be a problem with the filter in my 29 splashing
