I'm trying to setup a 90g Lake Malawi Cichlid tank. I have the sand already. Its standard white/brownish sand that you would find on the shores of a great lake. I plan to have a rock pile formation along the back wall of the tank going up about 2/3rds of the tanks height. I have 2 nice pieces of driftwood that I'll mix in with the rock pile somehow.
What I cant decide on is what color and shape of rocks to use. I want them to be dark so the fish will stand out nicely against them. Some ideas I have in mind are:
-Flat rocks in a staggered formation
Example:
-Rounded rocks in a mound. Kind of like this but centered.
Example:
Volcanic rock pile. I would love to do this one but I cant afford it.
Example:
What one out of the first two do you like the best? Any other ideas would be appreciated as well.
