I have 2 7" temensis peacock bass and the last couple days have noticed they are picking on my rays discs! Looks like they will have to go in the other tank. The only tank mate I have kept with rays and no problems is a dang arowana.
 
I had two peacock bass 8 and 10 inches in with my motoros and they killed the smaller one......Best companion fish Ive found so far has been a tigrinus catfish.
 
My bass and aro are always biting my rays. Never rely does any damage so i dont mind. Its nothing compared to the damage done during breeding

My bass is pretty good about not messing with them now that he has been tagged 2-3 times. I would just keep an eye on things I have never seen my bass leave any marks and he is rather large 18" or so
 
my rays have killed a 17 inch tig and a 16 inch broko bass in the last 6 months, not to mention a 24 inch royal clown knife, a flag tail, 6 large fronts, and a sabalo pike. The first three were all darted. Tig lived for almost 4 weeks before he finally died. Messed up his nervous system cus all he could do is swim clockwise on his side. When he stopped swimming he would settle on his side in the same position. The bass and the knife both died in less than 18 hours from the time they were darted. The rest were just eaten.

Point is nothing is safe, ever. Keep other fish you don't care about or are easily replaced. Right now the last two survivors in my tank are a 30 inch silver aro and a 22 inch endli bicher. I really hope neither bites it but I wouldn't be shocked if it happened.
 
Well.... It's official... The only tank mates my rays are gonna get are more rays! I decided to leave the bass in for a couple more weeks... Well last night was their last. Ever since I put them in there my rays have not moved around as much and slowed down their eating habits, and started pecking at the ray's disc. Well Sunday night while I was sleeping they really tore up my male marble, one of the twins! And last week I started noticing their slime coat was shedding on my female motoro. Then she stopped eating totally. Well she ended up passing Friday. I'm afraid I might lose another one as well. Them bass aren't 8" but they have def done some damage to my rays. I am keeping the lights off and keeping the water perfect as possible and just hoping
 
That sucks, sorry to hear. You know the drill......GL
 
I've tried a lot of tankmates for rays. I've got some decent sized Lemon finned Barbs and a milder species of Brycon along with an Aro that all seem to fine as long as the rays stay fed, I slipped up and they got one of the smaller Barbs. The combo's been working 4+ months with the Barbs, close to a year on the Brycon and Aro. Most of the experiments gone wrong happen in a couple months.

The Wolf on the other hand didn't work. Rays got him pretty good, gonna have to wait till older.

Irwinnis are the perfect tankmate for rays. Gentle giants that do nothing to the rays and the rays can't do anything to them. They do great at cleanup after lights out too.

I've tried alot of other fish and continue to but at least there's a few ideas that I've had really good luck with and I think others will too if properly sized.

Good luck on the rays AJ! Hopefully after the stress is gone they'll be back to normal.
