That slime, from what I know isn't harmful, my bettas are perfectly fine, and I've a suspicion that the slime comes from the water conditioner...
Top Fin ornaments are not the best for your tank. Their ornaments messed wilth my water and made my fish sick. I highly suspect the paint they use is not fish friendly being made In other countries which do not have high standards on safety.. I won't go near a TF ornament with a ten foot pole.Also just noticed some other things.
1. The tank smells like wet latex paint sick when I stick my head inside it. Hereby vow to remove my cave decoration from the tank. By top fin, it's this thing: http://www.petsmart.com/fish/orname...rium-ornament-zid36-17503/cat-36-catid-300071
2. There is a reddish brown stain about an inch long and a cm wide (spread out) of what looks and feels like (rubbed a finger across it and it rubbed off) mud at the bottom of my tank. Is not mud for sure. Worst case could be my décor leaking paint?! don't think he pooped that big. It's in the general area and size of one of the cave's legs. :shake:
