<< Hi Folks,, > I too am very curious whether I could keep a mated pair of angel fish in > the same 20 gallon tank with my 10 apistos. > Thanks > Vicky >> Sure, Vicky, if the Apistos are not valued. They are too shy too eat under the pressure a pair of angels would apply in a tank that small, and too small to put up with the physical hammering they would take every time one of the fry got a half inch closer to them than mom and dad are comfortable with. And if the Apistos spawned also in a tank that size, they will not yield as quickly as necessary for their safety. Bob Dixon
