This is my setup of my first African tank. Mixed mbunas, synodontis cats, and a pleco. I found rocks outside my work from a project and cleaned them up and added argonite substrate. Added a piece of Malaysia driftwood. Sponge filter, 2 75 gallon hob filters. I was told they were all male at purchase time but a female was undercover. Ended up with fry. Mbunas are brutal . Only one survived and he is in there growing well. I found some odd hybrids that look really cool. Redempress/yellow lab mix, pearl orange blotch mix. I've learned by experience to keep them in greater numbers to avoid aggression. They are eating machines and I give veggie based flakes / pellets
