Lei Long fish must stay naked. Arowana reared in bare tanks is not easy to be injured. Arowana chases live bait, and the outbreak speed is extremely fast, so it is not easy to be injured by bottom sand when chasing it. In addition, fish infected by parasites or bacteria will relieve itching by rubbing, and they can avoid scratching fish scales and other parts without laying bottom sand.
