Limpet-like 'thing'

[Jim Lay]

Hi Folks. I've got some limpet-like crawlers on my tropical fresh water tank glass. These creatures are too small to photo. They are barely 2mm long, 1,5mm wide and .5mm high. They have a greyish clear shell and are just like sea water/marine limpets. They travel very-very slowly. I've no idea where they've come from. Anyone got any idea what they might be?

Hi and welcome to the forum

If you could post a picture or short 20 second video this will potentially help identify what seems to be the problem.

Best of luck.
