Who Gives A Fish Forums

im thinking of getting 10 Pseudotropheus demasoni cichlids, does anyone have any advice on male to female ratio? would be great to get some tips

I'd go with the general consensus, 1 male to 3 females is the way to go. The males really need those females around to bring out their full colour.

I'd advise against the 1 male to 3 female ratio for demasoni. To be honest, it's not the best approach for these fish. What you really want is a larger group of at least 10-12, with only one or possibly two males if you've got the tank space. The thing is, demasoni can be pretty brutal to each other, so having a bigger group helps to distribute the aggression.

I've had no issues keeping 2 groups of trios, so I'm not convinced big groups are always necessary. What are your plans, are you going to keep other Malawis with them or have a species-specific tank? And what size tank are you planning on using, by the way? Oh, and just a heads up, I'm actually just up the road in Maidstone, and I've got some Demasoni fry growing out at the moment.

I'm setting up a species tank, just for the Pseudotropheus demasoni cichlids, and the tank's 3ft, about 130 litres. Got 10 on order, due to arrive after Christmas.
