Thanks for all your help, guys! Aus, his poo looks pretty normal to me. Just regular brown poo. His bloat is completely gone... I have figured out that he flares and reacts when I turn the room light off but leave his tank light on, so I'll do that once a day from now on, and hopefully he'll stay regular. I also will cut back on his food a little bit in hopes of not getting him bloated like that anymore.
I really appreciate all the replies, this forum is awesome! I'm so glad I joined here, you guys are great! :)
