Mysterious cory problem
Ever since I have added my 8 cories, I have been noticing problems resembling chronic
illness with 2 of them. For one, they are physically deformed. One of them has a misshapen, swollen head and lacks the body profile of a typical cory(it's more cylindrical) and the other one has a huge belly that has nothing to do with having recently eaten, being gravid or any disease. They have not grown at all in 2 months and are now 50% the size of their same-age peers that came with them even though they all started out same. they both have seeming breathing difficulties and breathe very rapidly all the time, even in rest. They swim up to breathe atmospheric air 10X more often than the others and sometimes seem to lose buoyancy control for short periods before they regain themselves. They also avoid the other six and never show up when I feed them(I don't know how they survive). All other fish, including the other cories are in perfect health. I have run them through the gauntlet of all possible treatments(their symptoms were so vague I could not pinpoint anything) but they still behave the same. The only thing I can think of is that they have some genetic weakness due to possible inbreeding in the eastern "fish mills" What do the more experienced members on this forum think?

Would be ideal if you have photo in case there is other explanation. Having say that, if they come from farm or hobbyist, there is greater chance of deformity since weaker frys are given better chance to survive. Yes inbreeding can be a problem as well.

Thanks for the reply, Cory.
I have been trying to get photos but the ailing two keep on hiding(unlike the 6 healthy ones
who are currently trying to swim through the glass). I will post pictures as soon as I can.
