I recently added 1 male & 1 yellow female square back anthias to my 125 gallon tank. I know it's best to have at lease 3 females but the store only had the pair (in the same display tank) in stock, so I purchased them and figured I could add additional females later plus the sales person at the store said it would not be a problem as long as the females are close in size. In the stores display tank the pair seemed to get along fine but when I put them in my 125 tank the males always chasses the female away. I think this is normal because of having only one female in the tank, my I correct on this? The other question I have is about a week letter I added another female to the tank thinking that with another female they would start to school. the new female is a light pink in color with slightly darker spots on the side fins and I noticed that the tail fin is slightly different then the tail fin on the male and original female? Is it possible that the pink female is not a square back but a different type of anthia? The two females get along ok but the male chases both of them away and seems to want nothing to do with either one of them? Currently all three fish swim seperately around the tank and I'm not getting the schooling effect I want? Help please!
