mixed cory school?

[tomherndon]

All advice points to keeping cories in groups, but does group require same species?

I've got two 10gal community tanks and would rather mix a couple of individuals of different species rather than stock cories of a single species in both. [since I can't add more than a couple of a single species, can I get by with a single of a couple species] I'd like to ensure that they have a sense of community while keeping the view varied.

Both tanks have a few other midrange fishes, HOB filters with sponges for bio/mech filtration and some hardy plants.

For aquariums that small I would stick to the dwarf cories (pygmaeus, hastatus, or habrosus) since you could actually have a small school without overloading the bioload of your aquarium. You could definately mix species if you wanted some variety, as they will school together reguardless of the specific species.
