i keep getting mixed reviews on angels and different tank sizes. i currently have a 36g corner tank, 34" across 24" deep and 22" tall. its got a good amount of plants and 6 1" apisto agassizii. i've been throwing around the idea of an angel in there or two. i'm running an xp3 as a filter so im pretty good in that department. a LFS got some beautiful black angels in and i wouldn't mind picking some up. i have a 55g that i would prolly move everyone over to in a year or two when i get some more room. is this doable? if so how many would you recommend?
