I should have read up on them before I bought them, but I really didn't know what the Petco nearby would have (they're only pet store within 30min drive).
I looked around and knew I wanted some cories for my 10gallon. I asked the guy helping me in the fish department, and he said they'd be fine, but that they stress unless you have minimum of 3. After bringing them home I did some reading. Apparently they'll need a 20 gallon tank and are really optimal with 4 minimum.
I'm strongly debating returning them and getting a smaller cory. (I really do love the look of the emeralds, but they get 3".)
Unsure and worried about what to do, I'll call petco and ask about their return policy. What do you guys think?
*also suggestions for smaller cories that would work in a 10 gallon tank would be great. OTL
