Lol, no clue. I got him from a member and was bagged for me when I got him/her. Didn't see the mouth till I got home (was not happy about that). Owner claimed it was not like that Lol, yeah right. I doubt he kept in the bag in his tank Lol. Oh well, my fault for not checking since both were in a hurry.
I take it as a lesson learned... Don't buy a fish brought to your truck before buying. It bothered me at first (it was way worst, looks to be growing out of it as he gets bigger) but I'm over it
