Live Arrival Guarantee

The Yellow Cubicus can grow up to almost 2 feet and will require an aquarium of at least 150 gallons with plenty of room to swim. The Yellow Cubicus in juvenile form is easy to identify as having a yellow box-shaped body with brown spots. Adults the yellow fades and become brown. These fish are difficult to keep as they will nibble tube worms and if they become stressed they can release a poisonous that can kill fish in the aqaurium. Their diet consists of mysis, brines, bloodworms, and other meaty foods.

This fish is guaranteed for live arrival.
