Hello!

Has anybody successfully socialized a red devil in a large community tank?

I'm not going to put a Red Devil in my current community because it would turn things very volatile over time. It gets a little rowdy in there from time to time as it is a mix of central Americans and CA hybrids, and some convicts that quietly raise their children in a pile of jars (noble creatures). I have other tanks and it has taken quite a bit of juggling but I have no kills to violence and fins are intact, just a lot of posturing over territories and the seven feet of PVC tunnels throughout the substrate.

Through making extensive territories and blocking line of sight throughout the tank, and making plenty of homes, I have a red dragon FH, Fader FH, Red Devil x Texas hybrid, three convicts, two dempseys, in a large tank, with some tinfoil barbs and a pack of giant danios, of which I haven't lost a single one. Does anybody else have this luck? And more importantly, with a Red Devil? The guy I know who sells the pure devils (Amphilophus Labiatus), with the long narrow bodies and long faces and big lips I don't see anywhere else, says that he often has trouble keeping them around because of how much they abuse each other and their tank makes. But he keeps them in smaller aquariums in a store with high turnover....like a dozen and a half three inch devils, FH, GTs, JDs, and firemouths in a 55 gallon, and the larger red devils (5") he keeps three in what looks like a 29 or maybe even a 20 long (it is easy to know who is where on the totem pole).

Red Devil lovers and owners past and current, please discourage me from putting one of these noble creatures into my tank to inevitably lock faces with my flowerhorns, red tex, JDs, and convict children. I hate when my fish die, but I like the tough fish.

ehh ehh justarn justarn questions about red devils
 
My red devils live with 3 Texas, 1 Red texas, and 4 Flowerhorns currently and all are fine. I bred my RD so they been tank mates since very small. Even at 1 inch and a 12 inch FH he wouldn't even mess with them.


4 years no problems and then one day I had a very large male RD and he killed 12 fish in one day. No joke he killed all my texas, vieja ,convict large males, and red devils. He killed them when he started to spawn.

RD are a hit and a miss I had a 200 gallon tank and they're fine.

If he starts to mate he will kill all your fish. He can hook up with a FH, Convict and your red texas.

When you say large tank what are we talking about and is that your total stock?
 
how big is your tank? and how big are the current fish?
 
You socialize about anything with the right tank space.
 
The tank in question is a 150 gallon 6 footer x 18 in floor depth x 29 inch height. I have several large pieces of driftwood in it, seven foot of 5 inch pvc pipe hidden throughout with a couple large jars and a few small ones. Many caves made out of stone. All the territories face forward into the room for fish can chill in their spots without looking at their roommates dumb faces.

The stock is: 8 inch low grade flowerhorn, 6 inch golden/pink fader, 6 inch Texas x RD, 2 jack dempseys that I've found in LPSs completely black and bullying larger tankmates at 1' inch that are around 6 inch in length one male and one I think female. I have a paired up male pearl honduran red point 5 inch with a nice hump forming and a regular honduran red point cichlid female that is smaller 3 inch. An adult firemouth lives in the tank and a couple female blood parrots are in there one, one of which is completely full of eggs and ready to mate with the Red Dragon.

Other roommates who have lived here overtime have been: My EBJDs, a green terror, severum, and a male blood parrot who had to move because he got beat up a few times by the Red Dragon defending the honor of his boo (the female BP who is about to lay eggs again). We let the parrots try twice, he is infertile.

There are 6 giant danios and 6 tinfoil barbs, impressive eaters.

I run four emperors, a home make biological filter, and a sponger filter for filteration and I do a lot of water changes because I enjoy the animal husbandry. I have 55, 65, 75 gallon tanks set up around the house that I use to move fish around when I need to. I have dividers when needed. I also have a nursery now in my kid's room.

I know I have a full tank and I had more and have been reducing fish to a really ethical LPS as my fish grow larger and I'm figuring out more and more what I want. I know for example now I don't enjoy Malawi cichlids that much after keeping them for over a year.

I'm not putting a Red Devil in my tank now. But I would like a female, named Aunt Flo. The devils my LPS has are so bright red.
 
i have a RD 6-7" in a 125 gal right now with 2 3" dovii, a 6" jag, 3" GT and 2 small african cichlids and the RD protects all the fish from the jag and stops the fights in the tanks by getting in between the two with the issue, he is like tank dad
 
That's not a big enough tank for an aggressive community to have success imo. If you have peace now count your blessings and leave well enough alone. Your one hostile takeover from total chaos.

If i remember correctly what ive done in the past in a 180g+ tank. I started with like 10 labiatus and I think weeded out to all males. I got rid of any really hostile trouble makers.

Yeah I know the end-game is cruising for trouble, but whenever I bring up the inevitability of fish Ragnarok to my LPS he tells me that I'm a fatalist and that I "am just a worrier". I'm a social work program designing guy so this is true, if oversimplified.

I'm not married to any fish. One fish guy told me when I consulted him about this that if the powers in the tank are sufficiently balanced then it doesn't happen overnight and warning signs, or omens of fish Ragnarok, can be seen, in the form of stressed out fish, torn up fins and lips, and of course, blatant belligerence. None of the fish now are bigger than the Bluegills I used to catch as a kid. I know if anything grows truly large (12 inch or larger) then I'll just have to rehome it,

If the flowerhorns go apeshit I'll either try to sell them on Craigslist since my local aquarium society discriminates against hybrid fish (I wonder what their opinion on my beagle-border collie dog hybrid is...) after sticking them in a 55 with a divider. I love my Red Dragon though...so much personality...you can see the amphilophus in the way he acts and he takes shrimp pellets out of my hands and lets me pet him and he doesn't attack me at all....the only fish whose ever bite me, besides my hyperaggressive jeweled cichlid breeders, is my jack dempsey male, and he looked scared afterwards.

I was in a store the other day and seen a 150 gallon tank that was 4 feet wide and I remember the visceral impact of seeing an aquarium that tall with such a big footprint. I remember when I started this and had small tanks and got a 55 gallon and thought it was the biggest thing ever. Now the 55 just had some guys growing out with my EBJDs and loaches.

I have Red Devil fever. I need to quit it, I have a good thing going. If I break the social contract now it will be all out war. I had a large Green Texas for a long time, King Rowdy, but he decided to fight with the flowerhorns, the blood parrot male that lives in another tank now, and the convicts, for two weeks straight (24 hours a day) and got stressed out and died with no wounds besides scraping himself on rocks being King Rowdy...he was incorrigible from the beginning but never caused any real harm.

The real fish on fish violence in my house ironically is in the peaceful community...there is a total alpha balloon molly that dominates the gourami, rainbowfish, and the one angelfish we saved from a chain (he was soooo ugly).
