My FH was fine when I got him and now his stomach is bloated and he's barely pooping. I have dosed the tank with epsom salt and metro because I believe it's from hex as he had some white stringy poop. He's from Thailand and had a small layover in California. I think I made the mistake of feeding him pellets even though I soaked them in the metro and epsom salt as well. He passes some poop and it's brown but not very normal - I have stopped feeding is this the right course of action? Camera is dead so no pics currently he's still energetic and willing to eat his stomach just looks like he swallowed a bouncy ball.
