Care notes

Venustus grow to about 10 inches and hunt by lying still on the sand until small fish come close. Males are quite aggressive towards each other but peaceful with tank mates too big to eat.

Keep one male with three to six females over sand with open swimming space; 55 gallons is the listed minimum, and a larger tank suits a fish this size better. Small mbuna, bottom fish and shrimp will be eaten.
