Here is a tad of info that I have learned about them:
These fish are truly original. The minimum tank size is a 20 Long. A pair will stay together for life, and if one dies they rarely will mate with another of their species. the male has a hump on it's forehead while the female doesn't. they guard and take care of their young very well. Spawn in caves. Great community cichlid. Don't swim but sort of hop. Neutral water and temperature is desired. Eat inverts. Grow to 3 or 4 inches(male is larger than the female)They are certainly an eye-catcher! Like a strong current, but one is not really required. Get even amounts of these fish so they can pair off. Arn't really agressive but can fend for themselves, especially during mating season.
Thats all I can remember for now.
They aren't too hard to keep for beginners.:thumbsup:
