Thanks Colin
I agree the blue and yellow ones are Acei but think the yellow ones are Yellow Labs rather than Red Zebras. The striped one I’m not sure of but looks more like a tanganyikan than a Malawi?
I agree with Colin that you will need much more stuff preferably rocks in the tank. Mbuna means rock fish so these species spend their lives in and out of rocks.
200 litres is going to be a bit tight for a mixed mbuna tank too - I’d have probably recommended a single group of Saulosi as your footprint isn’t the best right now.
