trio tank

is a 2x2x2 big enough to house a trio of cresties? or just a pair?

[DragnDrop]

In theory, it should be big enough for a trio. I've noticed sometimes one of the females will dominate the other female. If there's not much room to get away from her, the subordinate one might be too stressed or even get hurt. You'll have to make sure they get along well enough. After experimenting with groups, I've decided cresties do better in pairs, though trios do work for the most part.
