I recently setup a 29g tank with 3 black convicts. They are about 2.5" in length there are 2 females and 1 male. They have been in the tank for about 2 weeks now and I have plenty of hiding places/caves and rockwork.
The past 2 days the one female (the largest) is attacking the other 2 in the tank. Nipping their fins keeping them hiding or staying close to the surface. All these fish came out of the same tank at the LFS.
I thought that once paired off I might have a problem with 2 females and was prepared to bring the one of them back to the store. I never thought she would beat up on the male convict. but now since this has been happening i doubt the store will take them back since they look kind of beat up. I dont have room to move them to another tank but I also dont know what else to do.
Ive checked for eggs and dont think the atacking female has layed any yet but I dont know why all of a sudden she is attacking everyone else.
Any Ideas? if i dont do anything these other 2 fish are going to die. they are already stessed with nipped fins, loss of color and hiding at the top of the tank.
