so I purchased a couple of powerheads from someone I met online. While I was there he gave me a small frag of a mushroom for free, I was very pleased, my first mushroom I asked if I needed to quaretine the frag, he said he hadn`t noticed anything that he could warn me about and seemed kind of offended that I asked. Well when I got home I noticed Red Planaria flatworms. Not wanting to add to my quarantine tank eithier, I added it to a 1 gallon fishbowl with an airstone and I change about 1/2 gallon per day, each time trying to eliminate and remove any flatworms that I could see. So my question is after two weeks of doing so and not seeing any more flatworms can I now add to my tank or is there possiable eggs left behind not visable without microscope. thanks bigfish
