Hey guys!

I've recently been offered to take responsibility of a 92 (US) Gallon fish tank at a school and since i have one myself (albeit alot smaller) i thought why not!

The owner wants nice and colourful fish in there for the kids so i've landed on the Cichlids (he wasn't interested in any smaller fishes).

The tank itself is a Juwel Trigon 350, it's a corner tank, the idea is to do 25% weekly water changes (if this is not enough please let me know).

The filter is a Juwel Bioflow 8.0 Jumbo.

I need to know first of all how many fish i can keep in the tank and secondly what type would be best, obviously the more variety the better but i don't want that to come at the cost of more aggression for example.

Any help would be much appreciated, thanks!
