Red devil tankmates?

  • We are currently upgrading MFK. thanks! -neo
I had a 14 inch male flowerhorn who popped the glass so hard I could feel it. I thought no way he would ever accept tankmates. I tried it and he was very docile with other fish. You never know.
 
its very risky but i would try a mean oscar around his size since he is already a glass banger
 
hi just want to say dice devil wot are u feeding him cos ive had mine for days n he has not eaten n now hes turning on my plec :( help lol
 
i wouldnt put any other fish with him-but i would create some rockwork and get a cool pleco-- (ok maybe 3, and see who lives lol) and make sure they have places to get away from him until they get some size on them...
 
if i were you id set up the 220, and get maybe a 12" male jag or a 10"= buttikoferi (if you dont mind going away from the sa cichlids that you were originally after) butti's can hold their own easily with a RD id say.

let the other fish get established in the tank, leave the tank for about a month with the others in. then do a water change on the tank and put the rd in after the water change.

if this wont work then i dont think anything will tbh
 
Unlike many others, I've had better success with fish that are smaller, not the same size. It is easier to create hiding spaces if the aggressor is much larger than the submissive fish, and the aggression tends to be less IME as the big fish doesn't feel threatened by the smaller one.

I've found that convicts are a great choice for larger aggressive fish. They are smart, fast, and tough. Give them a bunch of caves and they'll fit in just fine (assuming they survive the first few minutes!). Introduce them carefully. The best thing would be to take the RD out until the cons get established -- 20 minutes or so.
 
If your rd is hyper aggressive not much will survive with it. I've had two. My advice would be, keep him in a 100g, put in a small pleco with lots of hiding spots and don't expect the pleco to come out if it's not dark.
A bad rd is not social.
 
I've had some RDs that i thought were agro and have separated but later on have ended up in community tanks doing fine. if you try it, try it with cheaper fish

woops didnt realise
