what's going on with my puffer fish?

[lossam8199]

hello,

my dwarf puffer fish had been acting normal until this morning I found him hiding under plants with an unusual big belly. He will only has round belly after I feed him with bloodworm, it's unusual because normally his belly will be flat. and he had a pop hang on him like a string of sausage. normally I feed him with 3-4 frozen bloodworms per day.

Sounds like he's either constipated or having bloat issues. Heavy bloodworm diets are known to cause bloat, so I would tend to think that's the issue. A healthier diet would be a variety of snails and frozen/live foods, with blood worms being more of a once a week treat/supplement.
