i'm not sure.but i'll try and find out if i can.
the bigger the tank the better,plenty of rock work for them to make their own territory(sp)
try and research what they need as much as possible,you can buy frozen cichlid
mixes from the LFS,and various cichlid pellets and so on,there is much they can have,and
need fore a healthy varied diet,they're not hard to look after,and you can have a tank
with nice colourful fish,you need to research carefully which ones you want,as some
are very much more agressive than the ones you have.
what is the PH of your water ?
preferably get an API water test kit if you can, you can't really work with LFS saying
"yeah your water's fine"
sorry if you know this already,i don't want to appear pushy.
