Although these are African cichlids, they are actually cave spawners from Lake Tanganyika. The one with the brownish body and yellow fins is Neolamprologus pulcher, this form used to be called Daffodil in the UK, the one with vertical bars is Neolamprologus cylindricus and the yellow one with horizontal stripes in the cave is a Julidochromis species, perhaps J. regani. All of them are very nice fishes which do well in aquaria.
