What would you recommend as a substrate/ decor?
I have a fine black gravel roughly 3mm grain size and a large mopani wood root in there at the moment with a few airating plants.
sounds good. i would add some rock caves as well. i much prefer sand to gravel and so do most cichlids. yours sounds fine. also, if you do go with the shell dwellers lots of shells would be good. with the plants that depends on your fish. a lot of cichlids don't need any at all and some won't work well with live plants cause they dig to much or will tear them up.
hey, let us know what you went with
