Well, 2 would not quite make as a school but it's a start.
Personally I learned the lesson of not getting 1 cory at a time. Especially the spotted kind. Since some of those spotted cory, I just can't seems to find the perfect match.
Let alone the right name of the specy. Some of them got some number for God sake. Poor fish look like prisoner or something.
Anyway, so now I got some mix bag of spotted corys. So I decided I should get some group of corys(6~8) at one time if I decide to get some new one. Especially the one with not so unique marking.
Although I still have some soft spot for the lone cory at the store.
Tend to pick them up if looks not sick nor too old. And if I believe I can provide better home than s/he has it at there.
2 is better than 1 but 6 or so would be much better. So please get them more Pandas if you have space. Then, they most likely would make some eggs if they get fed well and kept the water quality high. I think Panda is easy fish to breed. I got group of them in December and they've been making eggs ever since January every weeks(although I got several females).
And personally, I think the Panda is the cutest cory if you ask me.
