Fighting fish question w/ video

  • We are currently upgrading MFK. thanks! -neo
They are testing each other for dominance. You added a GT the same size as your JD, who has already established the tank as his terratory. It can end a couple of ways: They will each establish a section of the tank as their own. One of them will kill the other or will torment the other to the point it will be so stressed it will slowly start to fade and eventually die. That is an issue with adding fish like these to established tanks. A couple things you can try is rearranging the tank to establish new terratoy markers and remove the JD for a week so the GT can esatblish a terratory. This might help but they are so closly matched I doubt it will work or use a tank divider but the arowana it's going to be happy about that. Final answer take the GT back.

I agree, I rearrange, Or change the decor in my cichlid tank all the time.
A couple of times a year, I do a thorough cleaning on the tank and remove them all while I clean it.

What do you mean "240 gallon"? Are you getting one or are they in one? If it is a 240g, then there maybe nothing you can do. They might be fixed on killing each other. This has happened to me where I've had to get rid of one fish. A 240g should be plenty pace for one to get away or for 2 territories w/ out conflict.

That won't help in the long term. That is a temporary fix.

Thats not true. It could work long term if he sets up his tank so both dont have any thing to claim as territory. I did this with my 10.5" midevil. It would kill anything in its old 55. Even bit me a few times. Then I toke everything out including the sand. I left like that for 2 weeks. Then put my firemouths x convicts with her(it was temperary while I set and cycled their tank) put the sand back and instead of putting her cave I put my driftwood from another tank and were she would have normally killed all of them in like ten minutes they all survived but one that I put down cause it had duck lips disease.
