Is this normal? He only does it after eating. And I did treat for internal parasites and I didn’t visible see but I think he was just on a hunger strike. I did notice one time he twirled around/rubbed up against the sand and twitched. I think he’s bored too and he’ll be in the big tank very soon with lots of fishy friends. But that was only one time a few days ago other than that I’ve seen no white spots and he is his goofy loves me self who bit my finger twice yesterday lol.
