one of the angelfish nips at another angelfish. and the one that is being nipped at is just there, not swimming away. it doesn't look as if it is hurt. swims like the others, eats like the others, comes up to the front like the others when i am around. i don't understand. is this something they do ? or is the fish sick, will it eventually die ? just wanted to see if this was normal, or i should separate the one that nips.
i have 3 angel fish, all black, regular tails. their bodies are each about the size of a quarter. it's a 30 gallon tank. they're not staying in there forever, just for now.
the only other fish in there are a two mollies that never bother the angels and the angels never bother the mollies...and two snails. the water is perfect. they have places to hide and plenty of plants. the only thing i am not an expert on is angelfish, other than the basics. just wanted to know if this was normal, like between two that have paired off ?
any help would be nice.
