I have a new 44 gallon pentagon fish tank. There was one male platy in it and on Monday I went to a big aquarium store and bought some more fish (2 male guppy, 4 female platy, 6 zebra danio, 5 shrimp, 1 bristlenose pleco, all fish are babies). They all seem to be doing fine except for one of the male guppies is chasing the male platy who is chasing one of the female Platys. This was going on all day yesterday and when I woke up this morning the male guppy is still chasing the male platy although the female platy is now finally getting a break. Should I remove the male guppy? I don't want to get rid of the platy as he is my original fish and I like him. Thoughts? Why is the guppy being a jerk?
