Its been very mellow towards its tankmates. I have seen it cruise the tank during the day, but mainly to find a new spot to dig itself into. At though though thats a different story, it cruises the tank looking for food and its pretty entertaining to watch. Eats just about anything, not a picky eater at all. Nice lil cool catfish that is active at night and sometimes during the day. I'm pretty sure once it gets a lil more size onto him it'll be more active. Maybe Li has some moreinput on this. Thanks.
