Love the angels, I am planning a 55
gal tank around them. I feed them flake food, dried tubifex, frozen bloodworms. I do lots of water changes. I find platies, danios, plecos, and cory's suitable tankmates. Might add a few non nippy tetras and a spiny eel, but I have to watch my bioload (its kinda like your waist, if your not careful you wake up one day and its way too much
) I have 4 juvenile, 4 adolescents in a 55
gal tank with friends. As they get larger, I might have to move some angels out or lower the other bioload. Angels might chase off a few faster moving fish, might pick on a few slower fish, but overall they seem happy to show everyone who is boss and then let it drop after a while.
Just scored some "pearl white" angels that are beautiful. Look for them.
