Do Red Devil Cichlid...............?

Angels are really too delicate to keep with other cichlids. They don't move all that fast and the long tendrils that come from the points of their fins tend to be irresistable for other fish to nip. Angels should be kept in either a species only tank or with very placid, peaceful fish, like cories or the smaller ancistrus species, like albino bristle noses. Neons are the natural prey of angels in the wild and even livebearers like guppies and mollies tend to like to nip angelfish fins.

No. I have been breeding Cichlids for a while and I do have a main community tank where I keep my best breeding pairs together. I have had great luck keeping large aggressive cichlids together, but as for "Dither" fish the only thing that has worked are Large Pleco's and Silver Dollars. I have tried to introduce large 3" tiger barbs in a community of 24, only to have my larger cichlids treat them as feeders. Giant Danios also don't work. The problem is that they need 2-3 days to realize that the bigger slower fish are going to eat them as they adapt to their new surroundings. If you can get them to make it past that, they should be ok and the cichlids "should" leave them alone. But this should really only be reserved for advanced fish keepers with spare tanks to re-home fish into. Red Devils and Midas Cichlids (often confused) are hit and miss. They can have mild personalities or they can kill everything in your tank. 55 Gallons is not enough for even one, I wouldn't keep one in anaything less than 90 gallons personally.

most red devil's are very aggressive to any tank mate but angel fish would be the last type of fish i would ever put with one, you could try a gar, the pet shop by me has a 7" red devil with a big gar in a 90 gallon and so far so good, they have been together for a few months now and the gar is the only tankmate the red devil hasent killed, if you google red devil tankmates pretty much every site will tell you that there are no good tankmates and their better off alone

Red Devil Angelfish

From my expierience angel fish are not the most hearty fish and i think the chitlids would pick on em
