The Marbled Sleeper is one of the very few members of its subfamily encountered in aquaria. (Butis butis—the highly adaptable, so-called Crazy Fish—is another occasional find). Like its relatives, Marbled Sleeper is predominantly a bottom-dwelling predator. It can grow to a large size and is not suitable for beginners.
