i don't know yet - had a look around a few shops this weekend and like the look of them both. can you mix malawi and tanganyikans? if not is one better than the other with regards to ease of looking after, feeding, health, aggressiveness etc?
thanks - i've had synodontis before so will try that. how about corys, would they be okay with the cichlids as well?
going back to the substrate question, i know that sand will be better for corys / catfish etc, but anyone know if sand or gravel will be better for the cichlids themselves? or does it make no difference?
