Description and behavior

The blue botia has a long, compact body and arched back similar to many other members of the Botiidae family including clown and yoyo loaches. Wild specimens have been found up to 10 inches, (25 cm) but those in captivity rarely grow larger than 6-7 inches. (~18 cm)

The body is bluish-gray and the fins are red, orange, and in rare instances yellow. Immature specimens sometimes have a greenish tint to their bodies. Good health is indicated by bright coloration.

Juvenile blue botias are active schooling fish. As they grow older, they spend more time hiding in caves or under rocks in solitude. Like many loaches, blue botias are a nocturnal species that comes out at night to dig through gravel and substrate for food. They are omnivorous, but prefer a meat-intensive diet of krill
