two species in a tank?

[Howe]

hey,

I'm just curious rate now I've got a 56 gal thats heavily planted with 9 agassizi's (1 male 8 female) and a local pet store is finally getting in cacatuoides
can I possible have both in the same tank?
just worrying if they can interbreed, or any other problems I might incounter?
territory I'm not too worried over as I'd be re-doing the tank to mess up territories anyways.

A. agassizii & A. cacatuoides should do well together. It is highly unlikely that they will cross. The problem that I see is that your 56 is probably close to maximum for territories. Adding more apistos will probably result in the loss of some fish due to territorial aggression.
