So recently I noticed my one snail has some hair like stuff growing on its shell. Anyone have any ideas on that? And secondly I just noticed these little things on my glass. They are super small star like and kinda see threw and have very small hair like things coming from them aswell. Please help me out if I need to get rid of them or if they are ok. This is my first tank and still very new at this so any insight would be great. Thanks in advance.
