inter-cory relations

[dax29]

I've got a Sterbai cory in one 29 with 2 three-lined cories. They are all about 1.5". The Sterbai is acting very frisky towards one of the three-lined cories. I'm not concerned with interbreeding or raising fry or any of that stuff. I just thought it confirmed some of my suspicions that corydoras of different species can be good tankmates for each other and thus eliminating the need for all of them to be one species in order to make a healthy troop. The 3 cories seem to hang out a good deal and the Sterbai doesn't seem to mind that the three-lined cories cost about 4 times less.

Corys do best in groups of the same species, but will do OK with other species, yes.

So it's better to have a cory in a tank with different species of cories than to have a cory in the tank as a single species specimen? That's what I think anyway.

Corys are always better in groups, so if its a choice between a lone cory and a mixed species school, always choose the school.
