I have a 90g tank dedicated to the Madagasar cichlid Paretroplus kieneri. There are ten adults in there, seven of which range from 5-7", and the other three are younger and smaller, about 4". On April 4th, one pair, after a couple of days of vigorous pre-spawning activity, put down a spawn. I missed the actual event but took some video of them guarding their eggs. I pulled the eggs after 24 hours and tried to hatch them artificially but a large portion of the eggs fungused. I'll get it right the next time. Nine eggs hatched after 5 days at 86 oF and after about 7 weeks are now about 3/4-1" long and doing great. Here's the video.
