anthias aggression

[poknsnok]

I have 4 Lyretail anthias, 1 of which became a male about 6 months ago. For those that have a harem you are familiar with the male "charging" the female at times usually around dawn or dusk (tank time). Has anyone noticed any agression towards other fish, especially chromis? I have noticed mine charge my pair of large green chromis which is now 1 green chromis after yesterday. I found one near death with blemishes and marks on its side..

Yeah, the male will get agro on everyone.

great... so much for adding another shoal of chromi

I think it depends on the fish (both the anthias and the other fish involved). My lyretail male chases his females, displays to the other male anthias (bartlett and dispar). He pays no attention to any of the other fish in the tank (argi angels, flasher/fairy wrasses - all smaller than him).

Chromis like to pick each other off, one by one. I'd suspect the other chromis first, IMHO.

I will add that it also depends on how big the tank and how much swimming room they have as well as rock space to hide in.

Now with the above said I had one lone blue green chromis double in size and could dodge out of the way when the male anthias decided to take it out on everyone.
