Well there was a successful breeding - the cardinals are nearly as bad as those orange monsters and approx 1/3 of 100 gallon floor is not accessible from above so if they keep the young frys in that area the tetra never have a chance to go after them.Obviously not a tank for successful breeding of apistos.
This should read the cardinals at NOT nearly as bad as those orange monsters. Sure they will go after frys if feasible but as long as the parents keep them low there isn't much of an issue at least in this aquarium. The orange monsters will not only pick off frys that go high but go under drift wood if the parents are distracted. I've moved all but one to the a. ipirianga aquarium - the one - well he sees the net and now dashes under the driftwood so one day i'll snag him but after a week i think i've been out smartedWell there was a successful breeding - the cardinals are nearly as bad as those orange monsters and approx 1/3 of 100 gallon floor is not accessible from above so if they keep the young frys in that area the tetra never have a chance to go after them.
But yes i find these larger aquariums not really suitable for breeding for various reason esp if the frys need help with food.
