Cory Questions?

[mostlycichlids]

I have three albino corys - should I get more? The 3 Muskateers seem as happy as clams, but hey, there was a 4th Muskateer!

It depends on your tank size, but I feel they do better in groups of six or more.

a group of four should be fine, and they like to burrow in sand but round gravel is fine. you should be able to find fine-grained gravel that is almost like sand, but still big enough to be gravel vaced. i have seen tanks that use it with corydoras, and the corydoras burrow in it just as much as they do sand. you can also make a sand pit in a gravel substrate by surronding the sand with filter floss to keep it from mixing with the gravel
