Devils and tankmates

[Dgmannn412]

I have what I believe to be a large red devil midas cross. It has had tank mates in the past and I'm going to say that tank size sexual maturity and nature of the beast is why it is currently on its own. I am referring to it as it because gender is unknown by even the best. My question is what can have even a chance in the water with a fish of this temperament. I have watched it destroy pletcos jaguars other Devils parrots Dempsey s and many more. I'm going to move it into a 180 gallon tank and what I'm hoping is the added real-estate will allow for another fish to share the water. Again tho what in the hobby will stand up to a 3lbs devil with no concept of cohabitation? Im thinking buttakoferi or Dovii but I'm also remembering what it did to a jaguar that was bigger than the fish in question so you guys know what's what help me out.

I keep my Midas large ones with flowerhorns, convicts, vieja and you name it. The more the fish the better the aggression will be spread out

I have had some MidasxRD that I kept with all sorts of things......then I have had others who are brutal psychopaths who won't tolerate anything. I once had one I named Tilikum because every time I had to go in the tank with my hand it would always get shreaded by him. Its all about tank size and hiding places and experimentation however some just won't tolerate anything....my RDxmidas Tilikum even messed up a plastic plant pretty bad.

I had it in a 75gallon with 20 plus Africans and it destroyed everything in the tank to kill all of them. I get the whole over crowd and the aggression will seem as tho it's spread out but I don't know if this fish will tolerate any living presence in the same water. I've watched it mangle a tank full of bigger predator fish as the new fish. Then the guy gave it back and said he couldn't let it kill any more of his fish. So again what's the toughest most unruly fish you can come up with? Spending a fortune on multiple big fish is just going to give it expensive targets. I want something to put this fish in its place. And not just reassert it at the top of the food chain. Flower horns are 300 plus dollars here that's a ridiculous investment to let die in a couple minutes

Putting him in his place might mean he himself gets killed. I'd personally keep him alone in the 75 and go another direction with the 180. Aggressive communities with monster fish like that are a headache and a half.

Good luck with whatever you do, investing in a divider might save some lives.

You may just have a loner. A 75 is really not a lot space for a fish like this. Also tossing new fish into a tank that's established by another is not a good idea. Its a total pain trying to make an aggressive community work and requires a lot of trial/error. Plenty of space and walking the fine line of controlled crowding would be the way I would go. You can make about anything work with enough tank space.

What I would do is get a new tankmate and take the RD out and put him in a 20 gallon for a week. That way hell be the new fish in the tank and might behave better. Works for me whenever I have a bad fish I give him or her a time out and introduce them again and rearrange the tank and usually works out. Not always though. I have a 200 gallon so a 75 is already cramped up

At this point I think I'm just going to let it stay in the 75 by it self. It seems to be content and it has plateaued in growth for now. I just wanted to know if putting in a tank more than double the size would definitely calm it down or even allow for another equally aggressive fish to cohabitate. On another note what are the chances of keeping an arrowana with a saddle bichir and an oscar. I don't know the limits of an arrowana but I'm pretty sure that the oscar and the bichir will not fill the 180. Will the arrowana out grow the tank or would it max out and try to eat the oscar? I don't think the bichir would have any interaction with it being the bottom dweller it is. So what are my chances of success with that combo?

Yeah mate, I'd personally go a Parachromis. I have successfully done it with my own male RD who killed every other tankmate I'd tried previously. I popped in a female Dovii and somehow they actually paired and mated! I wasn't expecting it but I'm gonna grow a few of these babies out and see what they end up like

Imo, if your Midevil is a known killer it needs to be solo cause they only have 2 modes cohabitate or kill!
