I have a 200 gallon fish tank with 9 blood parrot cichlids. I've been noticing these little worms wriggling close to the top of the water. I assumed tat they were planaria, what do I do to getrid of them? and wht is dropsy?
No gravel and 100% water change... ? I thought substrate was required for a healthy aquarium? Also, with a 100% water change, you're removing all the good stuff from the water as well as the bad.
