Squareback Anthias killer female

[Tito]

I started with 2F/1M in a 125 Gallon. Within two days the male was dead - tail was bitten badly. I then added another female slightly larger than the other two. She was dead in 2 days as well! The area just behind her Pectoral fin was bitten very badly. The only other fish in the tank is a 1.5 Royal Gramma. For some reason the female that came with the suspected killer has not been touched. I think I know which is the killer because she seems the boss of things. So I'm thinking I have a vicious killa female in their. Is this possible? and if so, will adding four more fish change the outcome? Or, will this female continue to kill?

It sounds to me like you have two fish that are in the process of becoming a mated pair. The aggressive female is most likely transitioning into a male. Once she completely changes it is possible that he will more readily accept others. Until then, I'd just leave things the way they are.

Just a guess, though . . .

she is probably turning into a male that's why all the aggression is occuring. It is a very common event in the Anthias species. It's a random thing that occurs very often and to most people

Thanks for the replies and I'll have to agree with them. I'll wait it out!

Try taking weekly photos of her in the same orientation. It would be interesting to see the transormation progress as a pictography!
