Bloated betta, hasn't eaten for weeks

Hi there,

My betta seems to be strangely bloated, and refuses to eat. I got this betta three weeks ago, and for the first three days he was eating fine. However, after that, he stopped and displays very little interest for food. Since then, he has eaten nothing except for maybe 2-3 flakes that he spat out after eating.

He displayed no interest for food during these three weeks, until this mid-week, when he suddenly became extremely hungry. Like I said before, I'd give him flakes, he'd attack them viciously but then spit them back out in little pieces. This only lasted for a day, and now he is once again uninterested in any food.

I've tried feeding him peas, but he doesn't even notice them and they just sink to the bottom. I tried freeze-dried blood worms to, but again, he doesn't look at them.

I did a 50% water change every day last week, this week I've been doing the change every other day.

Yesterday I noticed that he was a bit bloated, and every once and a while he'll blow these "sick bubbles" that kind of look like bubble nests, but with larger bubbles.

Here is a picture:

What should I do? Is he constipated? Could he be, even though he hasn't eaten food for almost three weeks?

None, he has a java fern and some java moss though.

What type of food do you feed your betta fish?
Betta Color Bright flakes, I also tried San Fransisco Freeze dried blood worms (he never ate them though.)

Well, in the first three days I had him, once a day. Since then I put in a flake everyday to see if he's interested, if not, I take it out.

I think it's very likely that your fish has some kind of internal parasite infestation. Fish that have internal parasites often lose their appetite and develop a distended belly. I would purchase a deworming medication with the ingredients metronidazole and praziquantel, such as Jungle's Parasite Clear. You should be able to find this at any Petcosmart, but you might want to call ahead and make sure they have it in stock before you waste your time looking for it.

Generally, fish respond very well to this treatment and begin passing their worms (in the form of VERY big poops) within about 4-5 days--after this, they tend to start eating and perk up very rapidly.

Have you seen your fish pass any feces lately?
