Lol I'm probably not the best person to ask as most of my experience and knowledge comes from killing them.Ha yeah direct sunlight will do it!
I didn't know you had an african cichlid tank - which is what i am looking to set up next.
You got any tips? i live in a soft water area so i'm a bit worried about keeping the PH stable
I think you'll be fine as long as you add a ph buffer with water changes. Luckily my area has a pretty high pH by default.
From my experiences:
Don't mix most mabuna with peacocks unless you want to see a $10 fish massacre a $50 one. Yellow labs are an exception and are a must. Screw red zebras..
Get cookoo catfish, they look awesome and unless you are trying to breed cichlids are a great tank mate.
Give up on any aspirations of a planted tank. They will destroy everything. Everything.
They like sand better than gravel. Get playground sand and wash the heck out of it if you want to save yourself alot of money.
Caves. Lots of caves.
