Midas and Red devils are, to me, the most aggressive fish when they get big. No fish in my opinion can be kept with them in 500 L or better tank. I have been in this hobby for 10 years and kept many cichlids, but the red devil and midas are the worst fish to get in your 200, 300 or 500 liter tanks...it will be the only fish living in it eventually. :)
I truly enjoyed reading everyone's comments on their pets' behavior and character. They were all most interesting and quite amusing. I arrived at this site searching for an answer to exactly what kind of fish I have. When I bought her I asked for a Red Devil and what I got was an ugly little grey striped fish! She hid under a piece of drift wood and didn't come out for three days, so we named her Woody, but since then she has surprised us by laying eggs, so sometimes call her Woodette. She's really quite a character and is like someone termed, an aquatic dog. I can walk her across the tank with her following my hand back and forth across the tank. She lets me pet her nuchal hump, sometimes rubbing into my hand, but when she lays eggs, she becomes extremely ferocious to the point that she will attack the bubbles that spew from the pump, and will try to attack the dog as she walks by her tank. Sometimes she hits the glass so hard I'm afraid she's going to break the aquarium! Once she attacked the syphon as I went to suck up the unfertilized eggs, now I know better. What a catastrophy! She literally freaked out. So, now I wait to clean her tank until she realizes they are not going to hatch and disposes of them in her own way. She's a little over 2 years old now and is slightly over 18 cm long, but she's in a 125 L tank. She's grown a nice size nuchal hump, is grey with black stripes, orange eyes and thick lips on a pointed face. When she lays eggs she turns pinkish around the gills. I don't know if she's a Red Devil or a Midas...
I have a 200 L aquarium situated in my living room. I have two midas cichlids, one male with a huge head and a female who gets harassed quite often. As my mom and other members in my family walk by, they seem to follow them. They are definitely the dogs of the aquarium world. I've had them for a year and a half and they're already 25 cm!
I have a 3 year old Midas cichlid living amongst a host of other cichlid species, several algae eaters species, a couple of 8 cm plecos, a 12 cm spotted pimelodus, one reclusive chocolate cat aka Striped Rafael cat, and a lone tiger botia. At first, the Midas would cower around some of the more developed cichlids in the tank (280 L) as he was but half of their size. Namely, a bumble bee cichlid of 8+ cm and a kennyi blue about 7 cm. Though he would tolerate much of the cichlid classic territorial disputes, he has now grown to a size of nearly three times the smallest Haplichromis which resides in this tank and seems to have become number 1. He is much like a puppy in his mannerisms, and often head butts the glass from adrenaline rushes when resolving a difference with a cichlid tankmate over gravel rights. I do fear, soon he will overtake some of the smaller inhabitants, and they will call him Bubba, and there will be many loose scales upon the waters surface, and bones upon the gravel substrate. Anyways, all fish a super cool, and a Midas cichlid would most certainly give you something to consider beautiful, boisterous and bashful.
Well I must have bought the pick of the litter! My 5 year old male midas is probably the most well behaved out the bunch in my tank. He gets along very well with my convicts and dempseys, but he is deathly afraid of my 33 cm pleco, who charges the poor midas at leisure. He must seem pretty whimpy compared to everyone else's.
