I want to set up a 50 gallon breeder style planted angelfish aquarium with two pairs of angels. I have been doing alot of reading on angels and understand that they need tall aquariums. My question is will a 50 gallon aquarium at 19.5 inches tall be sufficient for them? Another query I had was what are some suitable tank mates that won't eat the eggs if possible. In the end I plan to buy 8 juvies in the wild coloration and grow them out in a 20 gallon high. Then I will hopefully get 3 pairsa so I can place two pairs in the 50 gallon as more show pieces and then keep one of the pairs in the 20gallon high. One last question I have is whether angelfish pairs will raise fry from other fishes spawns? I was hoping of removing some of the fry from the 50 gallon so the pair in the 20 gallon could raise them without the fry being eaten.
