Hello,

I've been wanting corydoras for ages, but my tank is too small for a nice school. But then I found that there are dwarf corydoras! Hazaa!

I don't know which of the three types (hastatus, habrosus, pygmaeus) we'll get....

I have only two questions:

1. If I add my oto back to the 12g, will she school with the cories? Would it be better to add a few otos, too?

2. Are there any important differences between the three types I listed?

Thanks!

Lucy

I love my dwarf cories, they're super cute.
I don't think they'll school with otos. Cories are bottom dwellers and otos usually hang on the sides, plants etc.
One of the dwarf cory species looks very similar to otos.

If you have room I'd get a few more otos. I have peppered cories and otos and they don't school together at all.

Okay, thanks Lucy and Sue. Well, since they won't school together, I will get my little oto some friends like her. She seems fine now, but I'm sure she'd like at least a couple friends.

Hmmmm. I think I can do 6 dwarf cories and 3 otos in the 12g.

I'd like them to have a happy school so they're comfortable, but I don't want to stuff them in there either. Do those numbers seem okay?

Btw, I switched it to sand substrate last night because I read that cories like that. I have a big bag of the gravel media in a pantyhose sitting ostentatiously up front. Hopefully, I don't lose my cycle.

That sounds ok to me. I don't think the otos have much of a bio load anyway. They're so teeny.
