Aquarium Advice Newbie
We have a happy 20 gal planted community tank with good water parameters, but this morning poppa molly became very aggressive toward momma molly. I do not mean the romantic chasing that occurs from time to time and accounts for her pregnancy (probably still a few weeks to go), I mean streaking across the aquarium and nasty biting, leading her to look stressed and try to find places to hide. Is this normal, what could cause it? If it goes on, we'll probably separate her.
