Altolamprologus compressiceps is a Tanganyikan substrate-spawning cichlid. It was first typed in 1898 by Boulenger.
Altolamprologus compressiceps is laterally compressed and will grow to about 6 inches. This fish is not strongly sexually dimorphic. Males grow a bit larger and may have longer finage and deeper bodies than females.

Altolamprologus compressiceps is often confused with Altolamprologus calvus which has a similar body shape and is found in some of the same locations. Compared to the calvus, Altolamprologus compressiceps has a shorter snout and a deeper body.
Altolamprologus compressiceps is interesting in that it posseses very hard scales, perhaps an evolutionary adaption that allows it to move in and out of cracks in the rock without being damaged.
Altolamprologus compressiceps is found in rocky habitats. Distribution is noted in the table above.
Altolamprologus compressiceps is not difficult to handle, but it is a project since it is very slow growing. From hatch to sexual maturity is easily and 18-month to 2-year cycle.
I recommend a species tank and heavy rockwork.
Regular partial water changes are recommended. I performed weekly water changes equal to 50% of the tank volume.
In the wild, Altolamprologus compressiceps feeds mainly on shrimp and other crustaceans which they stalk patiently over the substrate and in the rocks. In the aquarium, they adapt well to a variety of meaty foods such as New Life Spectrum and brine shrimp flakes.
I purchased four, 2-inch individuals at a GCCA Swap Meet. I placed the fish in standard 20-gallon tank with a gravel substrate and extensive rockwork. The fish could be seen excavating regularly, although they spent most of the time hiding in the rocks.
About six months later, the fish started approaching sexual maturity at 2.5 to 3 inches and the largest fish, who I assumed was the male, staked out the "best" territory. Still, no spawning ensued.
At another GCCA Swap Meet, I met a vendor selling "Compressiceps Caves". These small terracotta spawning aids are about 3" wide by 5" tall and look a like a small toaster. Interestingly, in the wild Konings reports that these fish spawn in small holes or shells. Regardless, they seem to want a tight, defendable place to lay their eggs, so I quickly paid for the "toaster" and placed it in my tank.
Within two weeks, the fish spawned and laid about 40 gold-colored eggs in the "toaster". I removed the "toaster" to a 5-gallon hatching tank and the fry were free-swimming about 6 days later. The fry stayed very close the "toaster" only occasionally dashing out to eat the baby brine shrimp I fed them.
At seven weeks old, they are still not quite a half inch long.
Two-inch juveniles are $18–24 each. This fish also often available at GCCA Swap Meets and Auctions.
Altolamprologus compressiceps is a popular fish and can be found at many pet stores that specialize in cichlids. It is commonly available on a number of wholesalers lists, too..
