My friends has been saying that her bettas poop has been quite odd. She says that it's half red and half blue, not blended in between the two colours. She also says that he has been quite lathargic and sleeping alot more.
He lives in a .5 gallon tank, which is a problem that's going to be fixed soon, and it usually stays around 76-77 because the room is warm. She does 100% water changes usually every day, but sometimes every other.
I'm wondering if I should tell her to treat for parasites, or if it could be something else.
