when my fish were ill i removed my assasin snails because the treatment for the fish could have killed them .
left it a few weeks with the snails in a fish bowl with air pump and small heater, only fed them flake food that i made sink to the bottom. they loved it. daily water changes etc.
rite now fish are all better i went to remove snails from fish bowl to put back into my main tank.
but found lots of little thin red worm things that move in a thrashing motion,
what are they? as i dont want to introduce somthing bad back into my tank.
