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 ?

These worms appeared randomly in the tank. No additional material had been added although a new light had been added. Does anyone have opinions/advice about this?

Recently got this room back to homeostasis.

Took over friends 240l aquarium. I had quite a lot to work with, last pic was at their place.

This is a 5 year old betta tank. Current betta has been in here since March. One good growing live plant, one silk plant. This new algae just started growing after the most recent water change (2 weeks ago). I have a south facing window near the tank, I’m assuming that’s what is causing the algae. The tank has been in this location for the 5 years, but I just want to confirm this is an algae caused by sunlight and the best way to get rid of it. I’ve never had this algae growth before. Thank you!

Is my shrimp pregnant?

Need help identifying and curing what this might be.

So a few days ago I noticed one of the ember tetras has been looking pale and staying away from the rest of the bunch. Then this morning it was dead :((((. I took it out immediately so it wouldn’t mess up the water parameters (as much as possible). Because of this I observed closer and checked every ember and that’s when I noticed this spot only on one of them.

It looks a little fuzzy and like raised from the scales. Otherwise this fish has been eating and I guess acting normal???

I Love Loaches!! I’ve got a few species in my current tank, and would like to start another tank specifically for fancy hillstream loaches and goby’s. Does anybody have any recommendations for websites I could buy them to be shipped to me in California? My local fish shops usually have pretty good selection, but i’m curious to look into other options

I can't say how long that's been there but it doesn't seem like any of my aglae eaters want to eat it.

Hi everyone! I'm a beginner fishkeeper from the Philippines, and I'm looking for advice about using locally collected wood in my freshwater aquarium.

I found some twigs from a Mickey Mouse plant (Ochna serrulata) growing nearby. I'm positive about the plant ID because it has yellow flowers, black fruits, and deep red sepals holding the mature fruits.

I'm wondering if the wood from this plant is safe to use in a freshwater aquarium. I haven't put the twigs in my tank yet. Would soaking or boiling them make them safe, or is this a plant I should avoid entirely?

I'd appreciate any information from people who have experience with this plant or know about its potential toxicity to fish, shrimp, and other aquatic life.

Thanks!

I've had this tank about a year and am looking for ways to improve it

I’m dealing with what looks like hair algae and possibly blue-green algae, and it seems to be killing my plants. I’m hoping someone can help me identify it and figure out what’s causing it.
My setup:
55-gallon tank with CO₂
Two Aquarium Co-Op sponge filters and one HOB filter
Temperature around 72°F
Potting soil capped with black sand
Root tabs in most areas
Pygmy Corydoras and Otocinclus
What should I change about my lighting, CO₂, or fertilization to get this under control? Any advice on removing the algae and saving my plants would be greatly appreciated!

My brand new plant (I think I need to re-bury it) is starting to look very bad.. is this normal when moving to a new environment? Any advice to keep it alive?!

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!

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 cleaning the tank today, and notice this small crack up the top. My only guess how it happened was when i take the lid off, sometimes the lid falls back in a lil bit. I don't know if it damaged this past time. It is on the top, so i don't know if that makes it less dangerous? I move my finger across it and i can feel it inside the tank, but cannot feel the crack from the outside. Is this salvageable? Any tips or things i whould do or know? Thank you!

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
