well i want to get 3 silver angelfish for my 29 gal tank and i want to know if they will be compatiable with one another? and can i get them to breed with my 5 cories and 8 mollies?
Same species. They get along fine. I have two koi angels in a 29 gallon. The general rule is 10 gallons per an angel. The 4 should be ok without many other tank mates to dirty up the place. They do get about 6" long and high. When you have a group on angels sometimes one will become dominant and push the others around. And like people have mentioned, if two pair up they will pick on the third. The best case is if you get two pairs or if they all just get along.
