r/corydoras

Picked up some new julis and they are so damn cute.

This is Ludafish and Childfish Gambino, I got them back in April and they were at the time a little bit larger than Mou (who appears in the video as the baby). I am pretty sure they are bronze corys, they're definitely female so i expected them to be round, but jesus are they r o u n d, Especially Gam. Do they look like they are finished growing? They are shorter in length than my peppered cory, but definitely bigger otherwise. I have a growth comparison photo i will include in the comments but im just looking for help with what to expect. I will have to upgrade their tank overtime as my pleco grows, I am just hoping I have time before that because it means ill have to get an entire separate stand for the next upgrade as my surface can't hold the weight of a tank larger than 15 gallons.

I woke up this morning to one of them its whisker I have 8 buenos aires tetra, and five cherry barbs he seems to be eating good

Looked around on here for a bit before posting, but I’m curious. This lil fish is pretty active but I fed them brine shrimp a day ago and this guy now looks pregnant. I’m waiting a day or two before feeding him again because this roundness has me worried. It’s still very young as I raised it from fry.

I have the parents in another tank and they are almost two inches by now and round, but they are not Bruce the great white shark round.

Any suggestions? Worried for him.

These guys are just so freaking cute

So I had 20 gal with shrimps and corydoras. And I had a betta waiting to be introduced to it. I had a month or two run of the tank to make sure corys are in and settled and shrimps are settled. Moving in my betta. Everyone’s nightmare - he kills shrimps in this situation. My personal nightmare now is he steals Cory’s food. He’s so smart he follows where everyone eats and bites and enjoys the sinking carnivore pellets and gets bloated and fat. It’s unreal. I try to space it because of him. But I have over 40 shrimps including berried mamas. And 7 corys. And betta is just a glutton are you kidding me. Now I have to start a new tank if I want to keep him alive. And now my bigger and older corys aren’t coming to the feed spot because he steals and corys are fragile. OMG

Hello, I started my first 29g tank a couple of months ago. Did a full fishless cycle and made sure parameters were good.

I added 10 cherry barbs which did great for 2 weeks, and then I added 8 sterbai corys after that. About a day later, I noticed one was missing when I was checking on them, and found it almost totally white with eroded fins, and dead in the tank. Not a big deal, sometimes fish die I guess.

Fast forward about 48 hrs and 3 more had died. A couple of them turned white and faded rapidly, but looking closely at them when they seemed sick, it almost seemed like their fins would start to accumulate what looked like tiny cobwebs on them, and then they would start to erode, they could stop moving, and then just kinda lay on their side and die. The LFS was cool enough to give me 3 more, which have done well. Currently at 6, with one starting to seem sick again with some accumulation on its body again.

Here is a picture of the sick one now:

I know the picture isn’t perfect, but hopefully someone else has seen this before. The remaining 5 are doing really well and sifting sand and shoaling together some.

Here are my parameters:
Ammonia: 0
Nitrite: 0
Nitrate: 10ppm

Has anyone seen this before? Doesn’t seem like ich.

I recently (maybe 2 weeks) added 15 sterbai Cory into my tank. I’ve noticed iced there are a few very pale ones compared to the others and was wondering if the color will ever come in and or if there’s a sickness I should be treating.

Note- when they first arrived I treated them for internal parasites and they seem to be doing better unsure if that would cause anything.

Timeline, I’ve had the pandas since April of this year.
Last Monday I fed bloodworms (i feed them once a week to every 2 weeks as a snack). Then I noticed my filter glitched and wasn’t running. It could have glitched sometime between Sunday evening and Monday evening. I cleaned it out, plugged it back in and it dumped a load of gunk back into the tank. Did a water change and cleaned everything up. Tested water and everything was normal. PH 8, Ammonia 0, Nitrites 0, Nitrates 5.

Same day I noticed a cory was barrel rolling in the water column and on the substrate would kind of wobble sideways back and forth while resting but would self correct. It can rest normally on the sand. However when it enters the higher waters or darts to the surface it goes a bit haywire. Video shows it after it sank back down after darting to the surface. It stayed like that for four minutes until I netted it. Once netted it stayed upright.
Fasted for 72 hours, no improvement. Symptoms have not worsened. It can rest normally and move normally. But when it darts to the surface it loses control. So moved it to a floating container at the top of the column yesterday, that keeps it from crashing out when going to the surface.

Tried an epsom salt bath yesterday but netting and moving to a separate container caused it to lose control and go sideways.
Moved it back to the floating container. This morning I tried another epsom salt in it’s container and that worked much better, no freak outs. Did a complete water change after and added kanaplex today.

Does this seem like a swim bladder issue? Infection? Parasites? Am I on the right track with kanaplex? Or should I be trying something else?
This is the only fish showing any type of symptoms, everybody else is fine.

Seems like a long journey for a little Cory but it was really about 25cm along the tank 😄

They keep perching like little birds, it's so cute

Hi all, as the title says I realized I have 3 different colored pygmys. My og ones are with me for around 4.5 months or so, light grey one is with me for 1.5 month and dark grey one is with me for 1 month.

They all eat the same food and are really active, although I think light grey one is a bit less active than others (There is only one, I’ve got 2 but one died in its 3rd day).

All three groups were taken from different shops, there is 2 dark greys. I’ve searched about if they have different color morphs but couldnt find anything. What could be the reason?

lights are off in the tank and usually my sterbai cories all come to the front of the tank and huddle up to go to sleep, but i noticed that one of them is on his side slightly curled, picture is bad but there’s only so much a phone could do, clearly isn’t alright but not sure on what to do? i can see he’s breathing but had no reaction when i tapped on the glass but neither did his brother. there’s has been one that is more lethargic from the past week ish but i put that down to the heatwave in the uk. my father had also done a waterchange earlier in the evening. advice appriceated! had the cory since early june.
