So yesterday I noticed he was bloated so I didnt feed him last night. His behavior hasn't changed at all still moving around really fast, loves to hide behind plants, the filter, and heater, he even comes up looking for food when I open the hatch. I fed him a pellet to see if he still eats and he did. I'm not sure if this is anything I should be worrying about, or will it go away if I stop feeding him for a day or 2.
Here are some pictures. Its kind of hard to get a picture of him because he's always moving around so fast and when hes not moving he's hiding behind things.

You could try fasting him for a day, then cutting him back to one meal a day for a short time. Also, maybe feeding him a little daphnia. It's natural laxative and might help him poop, if he's constipated.

It's a bit hard to see, but he seems very active and doesn't look scary-bloated. See how he is after a fast/daphnia, and maybe update in a few days if he doesn't improve.

Is he having trouble swimming up or down in the water? If so, he is severely constipated and it has caused a swim bladder disorder. I would suggest fasting, bu tit could really be anything.

He doesn't have any problems swimming at all and what's daphnia? where could I find it

[wah543]

So I skipped feeding him for two days and now he wont eat and he doesnt seem as active he only moves around a lot if I tap on the tank where he's sitting, should start using epsom salt or something?

I am not an expert in diseases, I would ask someone else

Daphnia arevsmall shrimp like creatures. You can get frozen daphnia in ?pe stores, my Petsmart has them.
Don't tap, it will cause stress. Is he still bloated? Then don't feed, yet.

[Perseusmom]

You could try the epsom salt is one teaspoon per gallon and also I believe you need more water changes, 2 50 percent and 1 100 percent a week for your size tank. I sure hope he gets to feeling better real soon keep us posted to how he is doing and good luck !!!

He's still bloated I put epsom salt in the tank, I'll keep watching him, should I do more water changes with the epsom salt in or something? and I'll check a petsmart here to see if they have daphnia

Update: Second day of using epsom salts, and it looks like he's doing better, he's moving around freely again he's active again, he still looks bloated though, should I keep using epsom salts?
