Why my sevy chase other sevy?

[IMCL85]

Hi all Revently my sevy been acting very strange I have been doing 3 days per 50% water change nowadays due to illness. And after yesterday water change 2 of my sevy have always chased the other 4 to another end of the tank while they stay on another. Any one have idea? They still recovering from the bacteria infection I got from ich like 2weeks ago.

It could be they have paired up, but more likely it is because of the size of the tank. What size are your sevs? as they can reach upto 9"+ and 40G tank is far too small for 6 serverums, if they are over 4-5" i would say you shold remove the others.

I got like 5 of them at 6" and 1 which I think is the female at 4" before i have like 8 of them but 2 r dead during treatement and a black out killed them. I cant find any more free tank but a hospital 10 g which is far far too small for them. and I dont know if they could get along with my dicuse.

If 2 of your sevs are chasing away the rest of them, I'd say it's a good bet you have a pair. This is a good thing. Take the rest of them back to the fish store, sell them, or give them way, but it's very important that you remove them before the stress causes even more disease in your tank, or somebody simply gets hurt.
There simply is no room for more then a pair in that tank, and even this pair will outgrow it eventually.

arrrrrrr I see what else I can do right now those 2 just give the other 4 like about 1 other 7 swiming space.
