What to know before you buy.
With its tall, diamond-shaped body and striking black vertical bands, the Mono Sebae is a graceful swimmer. This is a shoaling species that must be kept in groups of five or more in a large aquarium to feel secure. As they mature, they require a gradual increase in salinity from low-end brackish to near full marine conditions.
