I believe I have Planaria in my one tank. The tank has a Piranha and I occasionally feed him Rosies that I get at Petsmart. So my first fear was that it was a parasite from the Rosies. I also added slate recently but I poured boiling water on them a number of times, which I read here that you shouldn't boil them. There are also two plants one grown from a seed I think its a type of lily, and a water wysteria that I bought a while ago. I do a 20% - 30% water change once a week and a use a gravel vac. I read that they show up when the gravel is dirty with uneaten food. But the piranha usually eats them whole, so I'm not sure why there would be uneaten food. I guess fecal material could support them or algae. The Nitrates are low so I was surprised to hear it was dirty. Reading I've seen that cleaning the gravel more and water changes will get rid of them but was wondering what else is helpful. Salt apparently should be added but I don't want to put stress on the Piranha at all.
My major question, though is where did they come
from. I'm assuming they didn't spontaneously generate, but they could be everywhere maybe but almost microscopic, or was it the Rosies. I use them because I heard they are cleaner than goldfish.
