Hey,

Well I recently have taken over maitenance and what not for my/my bros tank (he went to college).

Finally I got some new sceneray, fish, and cleaned the tank...hadnt been cleaned for awhile.

Anywas, today is the second day that I've had these new fish (2 of which are guppies, females i believe).

Just today I noticed that one of the guppies was hiding on the bottom of the tank next to a plant.....Then I realized she had nip marks on her back Fin (anal fin?). She hides now.....either in the rock i have, or just somewhere low..It is making me mad, cause whenever i put some food in, and if the one who has these marks goes to try to get some food, the other one will come and scare her away...im guessing that this other guppie is the attacker.

I put more food in to hope that some will get to this injured/atttacked one....i'm worried..

What should i do to stop this aggression, and should i do anything to make sure this other guppie heals?


EDIT:
Sitting here obvserving more....it looks like all my fish are going after this guppy lol.....well. not all, but my lemon tetra definently did, the other femal guppie seems to be just following this guppie at times, but i havent seen any actual bites, besides the aggression over food.

IDK...also, my zebra danio (kinda crazy guy....always going wacko over nothing) sometimes appears to be chasing the guppie...but idk
