Snail eggs probably - i take it they are on the glass?
Yeah, on the glass, will these become fish food or will I actually get snails ?
Yep those are snail eggs. Not likely to hatch but if your snails are spawning you might find a the odd small snail that survived.
No, will just probably be eaten/damaged especially on front glass...
Cool, I like the idea of it being food
quite a good free food suppliment
