When the clowns get too big I have a 125 gallon tank I can put them in. It has 2 Green Severums, 1 silver dollar, and 4 Blood Parrot Cichlids. As for the angels, the pet store I bought them from would readily take them back as they are constantly selling large angels. Mine are only about an inch long now though. I'm also not adding the gouramis, rainbows, kribs, hatchetfish, and upside down catfish. I'm only going to have the cories, horsefaced loaches, congo tetras, angels, clown loaches, and a gold nugget pleco. I also had 3 clown loaches in there for 7 years before. They were fully grown and very happy. They only died because we had a power outage, the water got cold, and all the fish got
ICH.
