I personally don't think it could be bad for the water, but maybe if a fish eats it or something... idk. I'd personally go in and pick 'em up with some tweezers or something just in case
I was just worried about them eating too. I'm hoping someone has an idea other than picking them up one by one. But if that's how it's got to be well then I'll get picking
Ya, the loach seems to play with them a bit but other than that pays no interest in it.
I think I'll net it then if I get some sand in it I can just pick out the bits and dump the sand back in.
