I also would recommend the C. Aeneus. Remember, cories like to be in groups. You will see them much more if you keep them in groups of 4 to 6. If they are kept in pairs or on their own, they will try to hide most of the time.
Hi Barracuda518
Yes, I do intend to buy at least 3 corys (of the same species) when I do find nice and healthy ones!
The corys that I saw today at a few LFS didn't seem to be as active as I thought they would, most of them stayed on the substrate at the bottom and barely moved!
I took this as a sign that they weren't really healthy and hence didn't buy them.
