not a fan. In a large group setting (say15-30 cories), I prefer to have at

it's better to have more as well, as cories don't (as a general rule)

I'm not interested in breeding fish, at least not now. I agree that it
would look nicer, and it makes sense that they would feel more
comfortable/secure with number of their own particular species.

hybridize. With the cat's you have, it may not be easy to properly identify
what you have, but like I said, these are general guidelines. )

Ah, okay. :-) I thought I'd mentioned that they're C. melanistius, but
I might have missed it.

Have you thought about adding one of your bettas to the tank to see if that
helps stimulate the cories? It may not work with all bettas because some are
natural bullies, but I have a betta in with a hoard of cories and they get
along just fine..

I'd rather keep my betta on my desk so that he's with me when I'm
messing with the computer. :-) (He's in a filtered and heated MiniBow
5.) Since I started this thread, though, we've seen them out swimming
around and playing; they just hide really quickly once they notice us.
Another possibility is that they don't like the substrate we have in the
tank; it's an epoxy-coated gravel that's probably too large for them.
We're planning on switching to sand, so maybe they'll feel more
comfortable after that. We also have new tankmates for them in
quarantine.

Thanks for your advice.
