r/corydoras

This cory warrants the comeback of yo mama jokes

I have eight panda corydoras in a 65 litre tank for about three months now, and they don’t always do this. But I changed the filter yesterday because the previous one was not working well at all and now they‘re surfing on the glass. This usually is done by two or three corydoras and they stop after a minute or two.

Is this a sign of distress? If so, is it the filter? Or something else? Or are they playing?

What have I done to deserve that look??? 😂😂😂 (Hoplisoma Loxozonum, 1/12)

Im fortunate enough to have a generator but I have no way to cool my tanks. They are pushing 81 degrees and its not going to be at its hottest locally for another 5 hours. Currently trying to freeze water bottles but they will be a few hours

Hi, so this Cory has been having a hard time. It seemed to develop fin rot which hasn’t gotten any worse but its skin looks a bit paler compared to the other black corys. We also got hit with a canallanus outbreak. Through all this (round 2 of worming treatment was yesterday and did a water change today) he’s been quite lethargic on and off for a couple of weeks. However today it’s just aimlessly swimming around the tank non stop. I feel like it’s likely not a good sign. No signs of the red worms anymore and all other fish are behaving normally. Testing water with API test kit and ammonia is 0, nitrates have been higher than I like (20-40 at times) and there’s been a slight increase in algae growth so I’m working on small and often water changes for a while to get water quality back under control. Also adding tannins. Anything I can try for this guy? Unfortunately we don’t have a hospital tank available and feel like any extra stress might tip him over the edge but also don’t want to risk passing issues to the other fish. Thanks for reading and any advice!

the fih is active, eats swims, as do all the rest of the fishes in the tank. this white something is not attached to the body, only to the fin. moves when tsar bomb swims around. been there for a week or so, i've thought that it's just rubbish or sth

You can see how small he is in this video.

Found this little guy yesterday as per my previous post and pleased to see him get involved with the feeding frenzy. PS, I have cleaned the glass since. Was obviously too excited to film and didn’t see the watermarks and algae on the glass 😂

Pip, my newest and smallest panda cory, scared me this morning. Turned on the tank light and saw him suspended and “caught up” in the water sprite. I thought he died. Went to get the tank tweezers and turned back around and he was gone. Found him back up in there multiple times this morning. Resting or poking around. I was like “you little brat!” Haha. My other corys have never done that so i learned something new. And yes there are areas of the tank he can reach the surface easily so it’s not him trying to get up there. He’s definitely doing it on purpose. Brat i tell you lol

I’m obsessed with pygmy corydoras! so tiny and wiggly. I started with 8 and have 18 now!

This 75 liters (19g) used to house a dwarf gourami who recently passed... My fish seller has restocked a variety of cories and I was hoping to get some, after replacing the bottom sand and micro pebbles with fine sand.

Here are the options:

* Green Cory.

* Julie Cory.

* Similis Cory.

* Sterbai Cory.

* Black Venezuela Corydoras.

* Gold Laser Corydoras.

Is there one you would recommend that could live well in this setup? Or would it be too small for all of them?

TIA!

Jeremy wants to wish y'all a happy 4th of July! Go outside, be patriotic, set off explosives, have fun!

I am going to be completely honest, I only vaguely remember making this. I'm a little disconcerted.

Eh, whatever.

It's pretty sloppy and the fireworks behind him make no sense, but regardless.

Happy birthday, America.

Had corys with sand years ago and I miss them but this is the substrate in my current tank - I fear it may not be fine enough for them

Came home from work and found this little guy. I’ve had 5 Panda Corys since December and was not expecting any babies at all. Made up! The Amano shrimp at the end of the clip shows how tiny this little one is. Hopefully this comes through ok when published, if not I’ll try and get another one.
