i think it also depends on the demensions of your tank if you want a bigger tang get one but only if your tank is bigger then 1 ft and 1/2 cuz those things get big and they would be able to turn around which would suck for the fish and angels 2 they start out all small and cute and then get bigger and bigger and bigger so i think it all depends on the demensions of your tank and i agree about the post above with the waiting and stuff cuz this hobby takes lots of patience
