Pretty sure it was tapeworms, we bought some parasite tablet things that look like alka seltzers. Guess our cycle is gonna wreck... oh well, I'll just buy another bottle of safestart I guess. >.>
Also, I think the StressCoat
+ actually started to kill the worms off earlier... I added a dose to my sisters aquarium while she was at drama class, and then we discovered this a few hours later. All the worms except one were dead when they came out.
