I may invest in one more angel however i guess i should tell you this...
My fish may only consist of livebearers, a few egg layers however i got two different species in my tank that should normally be kept in a group and yet they aint, because i am trying not to over stock, now what you just said would normally worry me, but from my experience with these fish so far, they are doing well for their conditions..
Now i have had my livebears from the very start, and they have gotten so used to me, they will now take food from my hands, now i went out and bought a bala shark (which i knew should be kept in a group, however as i said, i didnt want to overstock) a angel (which i didnt know at the time needed to be in a group of two or more) and a bristle nose pleco (which i fell in love with because he was so tiny, because originally i was aiming for a flyign fox) now i brought them home, typically the fish were timid, however i carried on my daily routine, now my fish tank is located by my computer, which is under my bed (Hi-rise bed) and so i am constantly going in and out pass my fish tank, which is currently right behind me, now i fed my liverbearer by hand, because it is easier to control the amount they eat when they do that, but not long did it take before the angel fish started coming up to me, first cautous, but then join the other fish and fed from my hand, he hovers under my filter because thats where there is little flow in my tank, but otherwise he comes out in the open as normal, which now shocks me because of what you said, as for the bala shark, i was worried about him at first, timid fish i ever got in my time of fish keeping, and kept swimming against the back wall, but he hangs out with my neon's as if they were one of his own kind and has settled in now and also is feeding from my hands... and everytime i do go passed the tank, since there aint much room and am geneally quite close to the tank they dont run for cover but carry on swimming around, now i do wonder if it is still ok i continue on like this, or whether i should get a second angel just in case?
