I noticed this morning that there top fin is torn abit on both fish i don't know whether they did this to each other or something else in the tank. But i should be adding another 2 today so all is good.
dont waste your money on anymore FF they will kill each other
its one per tank thats the way it goes
i had 6 small ones as i thought it would be great to have a shoal they were fine for 4 days then then they started killing each other off 1 by 1 then i was just left with one big mean FF
Sooooooo many people have tryed to keep more than one per tank
