Hey, i have just noticed three tiny 0.5 centimetre snails in my tank. Just wondering whether this could be a problem, whether i should remove them e.t.c, thanks in advance, Alex
Could be a problem if you get over-run but I've had the same thing in my Betta tank for the last few months and it hasn't got out of hand. I could probably count 5 tiny ones at any one time but that's it.
You could fish them out though, I did with my 60L and have seen none in there for about 8 months now so I guess I won lol.
As above, those with infestations always have an underlying problem such as uneaten food or decaying plants etc, and these problems are over looked and snails are instantly seen as the ultimate bad thing in an aquarium.
My opinion is, leave them be, they're your best friends, they'll eat algae.
