Hello- My fish are all pooping these white long strings. They produce them extremely often and expel them very quickly. If they swim fast, the part that's hanging from the fish drops off. The stuff is white and somewhat stringy. Some of the fish appear bloated. I treated with API General Cure and did a few rounds of that, but nothing. What could this be? Are these worms? If so, what type and medication?
