Hi all,
A lot of people have associated them with feeding BBS, but they definitely don't come with the brine shrimps, so it is another case of a lot of small prey items = plenty of hydra. They must come in with plants etc. and even if you get one it can spread asexually.

I don't know where they come from, I always have some and if I feed a lot of small Daphnia or micro-worms they really spread.You've got me concerned here Ali, not seen any in my tank ever so I do hope the moss is not the culprit, wouldn't want to bring dread on any other member.
