Compatibility Question

[Beasts]

In an aquarium with 25 square feet of substrate would anyone envision problems keeping a black ghost knife and two elephant noses? The tank is heavily planted and also has lots of driftwood and rocks for hiding places. The volume is 410 gallons. Information from people who have tried this particular mix would be especially appreciated. These would, of course, not be the only fish in the aquarium.

the ghost knife may get a little pushy with the elephant nose. their electrical organs may mess with one anothers', but in such a large system it shouldnt be much of a problem
