I am planning a 55 gallon planted tank with Apistos and a pair of Discus and some small tetras. Any tips would be greatly appreciated. I'd like, of course, both the Discus and the Apistos to spawn in this tank. Andy Hi Andy, I've successfully spawned first A. cacatuoides and then later A. agassizii, (sequentially, not at the same time) in a heavily planted 90-gallon tank with lots of caves that also contained a spawning pair of Discus. The Discus spawned on the leaf of a large Amazon sword plant. The Apistos and the Discus seemed to tolerate each other well in such a large tank with so much visual and hiding cover.
