I have used a 15x lens here to shoot, as you can see they are quite tiny, the "rocks" you see is the 'fluval' gravel I'm using now. What are these, snails? plankton? It's populating like crazy! I can see at least 50 of them in my tank!!!! How to control them, any ideas?
I'm pretty sure those are snails. That's exactly what baby snails look like in my tank. I have a ton of them right now. Do you have anything in your tank that might eat them? If you don't really feed the snails and they don't have algae to munch on then I believe they will just die out.
