hi, you havea really nice setup there, the questions im gonna ask for for criticism, but curiosity. does that scat get bullied by the cichs? i thought that they had to be in brackish water? and what is the current pH of your tank? you would need to get it up to 8.2 for optimum conditions for the cichs, but im not sure if the scat would like that ...
for my own malawis, i use marine gravel, and ocean rock, with a lil bit of spaghellti rock, this buffers up to 8.2, which really brings out hte colour of the malawis amazingly, but nice setup anyways.
