Hi everybody,
over the last week I've seen what I believe to be a couple flatworms pop up on the glass of my tank - and over the few days their numbers have seemed to multiply quite rapidly (probably about 15 of them on the glass now)
Just need to know -
1. what are they?
2. are they bad?
3. should I/how would I get rid of them?
thanks again!
