Are rainbow sharks a jumping fish? The one that is in the theard Color oF Rainbow sharks. Jumped out and i didnt get to him fast enough as i wasnt home. Is there anything that would cause him to jump?
Having one in too small of a tank might cause one to jump ship, er, tank. Also, if something were in the room that moved quickly and spooked the fish, say, a cat, or a small child, it might try to jump out to escape what it perceived as a predator. May have been chasing a moth. There's a lot of reasons....
