I recently received a baby ck about 4inch im worried he's not getting enough if anything to eat. He is homed with another ck much larger than the baby and an ornate bichir. Any suggestions? I could remove him to another tank but would rather not he seems quite happy in his tank now he swims all around and has no problems other than he's very thin and a little ragid looking was that way when bought felt sorry for the little guy.
