I dunno if one of them is sick or not. But the biggest of the bunch seems very pale. The others have that black stripe around there head? Well hers is very pale. I guess I should get her out and try to figure out whats wrong? I havent a clue. Ive been losing fish left and right now,so whats losing a cory too. :shock:

I can't diagnose the problem, but I would suggest that you leave the cory in with the others; being very social, especially in my experience pandas, the stress of being on its own in isolation would be adding to the problem, not to mention the stress of being netted and put in different water or with medications (which corys do not like). Particularly as you don't know the problem.

Pandas seem to be one of the more sensitive corys, as others have recently commented. Most of them are commercially raised now, which is why they are seen so often in stores. Some would think this should make them more resistent. But maybe not.

oh okay,thanks Byron. I will leave her be then. She seems active like the others,so hopefully its nothing.

That one keeps messing with me,at least I think its the same one...sometimes it looks pale,the black stripes are very pale. Then the next day,everyone looks fine. So i dunno. Some of them look darker than the rest. So I have no idea,I guess they are all fine then. When I feed them,they all come looking so thats good. Even itty bitty is doing great,he is getting so big. He should be fullsized in no time.

So,one is going tail up now. I noticed after I fed them. Dang it. I sure hope its gonna be okay. I will fast everyone tomorrow and check on them.

i joined another forum and this guy said oh its gonna die and become dinner. dontcha just love the optimism?? hopefully thats not the case at all.

Sometimes the best treatment is no treatment. If you keep a check on water quality (pH particularly in an established tank) and do the weekly pwc, you're probably doing the best. Trying to diagnose some unusual behaviour is not easy, and given the sensitivity of Corydoras to any chemical and medication including salt, I would leave them alone. Beyond this, two comments.

First, corys are odd fish at times; some have a habit of "fainting" and just flop over on their side and sometimes even on their back, motionless for several minutes but still respirating. After maybe 20 minutes they right themselves and swim normally. Some are more prone to this behaviour than others. I've had my present three C. panda since January, and about 3 months ago one of them did this faint; never noticed it prior nor since.

Second thing is that pandas for some reason are frequently difficult to maintain. I've mentioned elsewhere that given the fact that this species is now commercially raised, not wild caught, you would think they would be hardier rather than the opposite; this may indicate that tank raising fish cannot eradicate the fish's natural biological makeup. Most of us who have maintained various corydoras species for many years still find C. panda the most sensitive and delicate.

haha thanks Aunt Kymmie. I guess so!! I dont see any panda with tail up so far. But cant see anyone in the back of the tank. All will come out sooner or later...if I sit long enough in front of the tank I may see them all...
