Okay, I bought 5, 1.5-2 inch Managuensis, hoping for a male. Right now I have them all in a 55 gallon in aquarium. The tank has been set up for about 4 months and all the levels are perfect. I keep the aquarium at about 82 degrees Fahrenheit. I've raised one female Managuense before, and saw how it looked throughout all of its growing. Unfortunately I had to get rid of her because; with her constant laying of eggs (with no mates in the tank), and myself having to remove them all the time, she became incredibly aggressive toward me, and began attacking everything that hit the water, no matter what it was.
Anyway, I just wanted to know if anyone has had experience with these guys and can tell me some of the first signs of male or female. I know about the horizontal bars, spots, and hooked mouth.. I just wanted to know if there was anything else. Also, with the 5 jags in a 55 gal aquarium, I thought they could all co-exist.. I mean, they're only about 2 inches after all. However, one of the fish, as soon as they all got into the tank, began ruthlessly attacking all the other fish. It's not the biggest one, nor smallest.. But he/she has become ridiculously aggressive. Its eyes glow a red/orange, and all of its stripes and spots are faded. The fish has become almost a pure gold fish with red eyes. When all the other fish are in the corner, it resumes its comfortable behavior, gets back its colors and blue fins.. Just want to know if there's anything I can do to fix this problem?
Here's a photo of him/her in a fairly aggressive state:
Never before have I owned a fish like this, I've never seen a Jaguar cichlid lose all of its bars and just turn into a possessed looking fish.
