Small Peppered Cory

[mislisa]

hey everyone, i have 5 peppered corys in my main tank, and i'm worried about one of them. i've noticed lately that it's much smaller than any of the others (2 of which are female) and is slightly lighter in colour. also, his tail fin seems to be shorter than the other fish's. is it sick or what? it seems to be eating ok, but i just want to be sure.

here's a photo of one of the larger ones and one of the small guy:

sorry about the blurry photo, he doesn't like to be photographed!

thanks!

I very much doubt it has any problems if it came with the other batch, but so many fish are inbred these days they often have small deformaties which yes, could be a shorter tail. Perhaps its not the case with this guy though, he might just be smaller because....hes smaller! Just keep an eye on them really, dont over feed. (good chance he is male too, they are often smaller and slightly less colourful)
