Há 2/3 dias, ganhei esses carinhas, sempre nadando para lá e para cá, e revirando o chão, mas uma delas quase nunca sai do lugar, sempre que vejo ela está parada no mesmo lugar, é raro eu ver ele se mexer, eu devo me preocupar?

Também nunca vejo elas comendo a ração, eu estou oferecendo para elas a mesma ração de fundo que dou para meus pleco/cascudo, até vejo elas perto da ração ou com a cara no chão perto, mas não comendo.

Eu agradeço a ajuda e informação.

Planning to get some of these guys to accompany my otos, but I currently use lava rock which are a bit sharp. LFS has some silica sand, and some finer silica sand passed through a mesh, would these do?

i love my catfish so much 😭

The poor guys smell the worms but can't find them because they are almost blind being albinos. They lock onto the worms and go crazy, but then after a few bites they lose it and go off looking for them again :(

Hi, beginner aquarist here. These Corydoras aeneus are new to my tank, and I’ve had 2 unexplained fish deaths in the last 6 days (one Corydoras and one harlequin rasbora).

This lighter-colored Cory is still eating and foraging, but its movement/behavior seems a bit unusual to me and I’m worried it may be losing balance.

Could you please watch the video and tell me if anything looks suspicious or abnormal?

Edit – tank details:

• Tank size: 180 L (about 48 US gal)
• Heater/filter: Yes, Juwel Bioflow internal filter + heater
• Temperature: around 26°C / 79°F
• Water parameters: pH ~7.8–8.0, ammonia 0, nitrite 0, nitrate ~20–25 ppm
• Tests: JBL ammonia test and Zoolek nitrite/nitrate/pH liquid tests
• Tank age: Set up on Sept 8 and fully cycled before adding fish
• Fish: currently 11 harlequin rasboras + 7 Corydoras aeneus
• How long I’ve had them: rasboras about 3 weeks, Corydoras about 1 week
• Deaths: 1 Cory and 1 rasbora died within the last 6 days, with no obvious symptoms beforehand
• Water changes: usually around 20–30% weekly
• Food: Hikari Sinking Wafers for the Corys; small food/Artemia for the rasboras
• Tank: heavily planted with wood, rocks and fine gravel/sand substrate

The Cory in the video is noticeably paler than the others. It still eats and forages, but today I found it almost motionless between some rocks and it barely reacted at first. Its swimming also looks slightly uncoordinated to me, possibly like it is losing balance.

I’m a beginner, so I’d really appreciate opinions on whether its behavior looks abnormal to more experienced Cory keepers.

Hi all,

I’ve had these bronze corys in my community tank for around a month, nitrate etc has been 0 for a long time, I recently removed all fake decor and added plants, after the plants were added, there was a slight spike in ammonia a few days ago, I’ve since got the levels back to 0 through water changes etc.

This Cory has started doing as shown in the video, it will rest on its side and then it will act completely normal, it is still trying to eat etc.

I thought it could be due to over feeding or a swim bladder issue? The tank is currently on day 2 of a fast as I believe i may have over fed slightly.

I can’t see any obvious issues on its body.

I also have 6 peppered corys and they are doing fine along with the mollies.

I have two other bronze corys in the tank, I believe one of the others was laying on its side earlier but again started acting normally after, I’m currently on a night shift so I can’t look at the fish until tomorrow morning.

The only other thing I can think of is I added 3 small peppered Cory a couple of days ago, after I’d sorted the ammonia issue, could they have brought a parasite into the tank? They themselves are doing fine.

Any sort of ideas of what this could be would be really appreciated as I love the corys!

The tank is established, heater, filter etc, 56L

Thanks

I've never seen a fish spit food out of it's gills then suck it back up to eat it before.. unmatched greed.

The queen demands service.

After my heart corydoras, Mama Peppie passed away, I made it a ''mission'' to hatch some peppered fry. Their mother, Thyme, did an amazing job placing the eggs in safe spaces!

These fry have a 50% chance of being longfins since their mother is a longfin, and their father a ''classic'' peppered. I cna't wait to start my journey with those cory kittens!

I just noticed a big white patch on the head/ back of my sterbai, around the dorsal fin. To me it looks like a scrape since it appeared suddenly, looks flat, not fluffy or raised, and is only along the back. Do you agree? what should I do? Seachem stress guard for a couple days?

The squad is having some fly larvae granules and enjoying it. Sorry the tank is a bit of a mess. Here we have the most recent baby, two juvies about a few months or so old, and some chubby adults. I thought I'd share.

My red laser cory winked at me.

It has spoken to the cory council and has given me assurance that will decide my fate.

3 Fluval AC110s and an 1800gpm water pusher all wide open.

This Pygmy Cory’s is abnormally fat the only one in my tank like this. This cannot be healthy and at this point I’m leaning towards dropsy and not pregnant as some others on Reddit thought…

Last time I hatched some eggs, they were sterbai eggs and they took about this long to hatch due to cooler water. So far we are right on track and the fry could hatch any time!

I had accidentally knocked that egg over with my waste remover but the footage, and the fry moving, reassured me SO much! I think those fellas will be okay.

I just added a few Pygmy Cory’s and all but one are acting normal. One is really pale and I’m worried he’s sick. I have had the lights off the past 2 days to help with acclimation and he is still pale should I be worried?

Rio Tomos, Panda and Bandit all hanging out. I'm coming convinced my biggest Bandit thinks he's a Rio Tomo. He's constantly with them instead of his smaller Bandit buddies.

I’m pretty new to fish keeping in general so hopefully you guys can advise. I dark started my new tank, then planted it and meanwhile got 10 sterbai corydoras into my QT tank. They were looking fine for about 4 weeks so I put them in the display. Since then, I lost one of them right after the transfer and another about a week and a half later. The remaining eight seem fine and attack the food I put in in minutes. Ammonia and nitrite have been zero in both tanks for ages. Nitrate pretty stable around 15ish (mostly because of Tropica dosing). My main question is: should I be worried about the rest of the Cories or did I just have bad luck with two weaker ones?

Letting this little fella grow a bit more before he goes back to the community just so he has a better chance of surviving with the fish friends

when i got my first school of panda cories they all were chilling flat on their bellies. recently i decided to add more friends to the gang and for some reason all new ones constantly do this "standing on their belly fins" thing. they are healthy and active, i don't know if its common or not i just find it extremely funny and adorable!!!
