Solitary Confinement

[abiddle]

I just purchased a 6" male Jag and added him to my 180 gal community tank. There was a brief battle with my male JD who qickly submitted. And the Jag just avoided my 12" Oscar who is very mellow anyway. The problem, believe it or not was with my male Severum. The Severum continuously chased the submissive Jag for two days, so I have moved the Severum to a spare 29 gal tank (Solitary Confinement).

Do you think I should wait a few weeks for the Jag to get used to his new environment, and gain some confidence, then put the severum back in the community tank? Put the Sevrum in a tank with my Angels, Or return the Severum to the LFS.

Please help!

This for what ever reason is fairly common with severums. Especially if they are female green severums. The problem you are going to have it that once the jag decides to fight back it will easily kill the severum. Did you try rearranging everything in the tank?

Usually it will only take a few days, maybe a week. You may find though that when you return the sev, it will be the one getting beat on.

This would be my main concern. In my experience you've got three possible eventuations.

1) Jaguar gains confidence but is still docile and they live happily ever after
2) Jag doesn't gain confidence, slowly grows to adulthood, finally snaps, and kills Severum.
3) Jaguar gains confidence, beats up/kills Severum straight away.

I've never had any luck with confining fish of the same species though. The less dominant cowering fish will always be cowering or beaten, whether it takes an hour or a week after reintroduction.

Agreed. I don't think the severum could seriously hurt your jag, but it's probably just a matter or time till the jag realizes how to end it once and for all...

i dont understand why your saying it will kill the severum but noone is saying it will kill the jd like the severum is going to be targeted and all the other fish are fine. i think you will either end up with a jag that will destroy them all or a jag once establishes dominance over all fishes will simply leave them alone. i dont see it being a jag severum issue. its a jag everything issue.

rearrange the tank, wait for two days and then add the severum....i had this happen between my female green terror and a female jack dempsey..

I agree with fishguts.

The Jag minds his own business.
The JD is the one that started that fight, and the Jag doesn't mess with him or any of the other fish (Firemouths, GT, Silver Dollars, Geo, female JD). The 12" Oscar rules the roost, and everyone knows to just stay out of his way, but he doesn't intentionally harass any of the others.

I am going to try the advise of GTbEaSt.

If the Severum continues his harassment, maybe the Jag will get tired of it and defend himself. He has the size and the teeth to do it.

And I know that it is possible that when the Jag gets older, he may kill everybody, but right now he is a very mild mannered 6".

I rearranged the tank and put the Severum back in.

Everyone is trying to establish dominance and territory.
No serious damage, just a lot of bumping and occassional lip locking.
The big oscar will break it up when he gets tired of it.

This is the toughest Severum I have ever heard of.
I had two males to begin with and this one beat the other one up pretty bad. I had to take the other male back to the LFS.
