Been a while, I have snails.

I think it's been 20 years since the last time I had snails. Just noticed my tank is covered in tiny ones. Looking closer, I remember even tiny pond snails being more spherical, these look more like limpets.

They look like limped to me as well.

Anytime you see them on the glass stuff your hand into the tank and squish them. They're great fish food!

They are indeed few limpets of the family Planorbidae, subfamily Ancylinae. Same family as ramshorn snails. A number of similar looking genera and species, some now of nearly worldwide distribution due to factors such as global markets, aquarium trade and others. Harmless but annoying when in great numbers. They do constitute great food for fish, but many can’t eat them unless one crushes them.

Few - meant to be fw, for freshwater.

They're gonna have to get a little bigger before the inhabitants will bother eating them, I think. SMallest fish in there is something like 6"

The ratio of a 6" fish to a small snail is about the same as me to an Oreo. And I'll eat the ____ out of some Oreos..............

Let's see, for fun let's see...
Average male height is 171 cm, oreo is oreo is 4.5cm, so about a 38:1 ratio
The biggest fish in the tank is my 25 yo redspot pleco at about 1000mm vs the limpets at about 1mm(On the high end from what I can see, most smaller), so about a 1000:1

So, for a person somewhere in the region of a 1.7mm food. About sesame seed, not oreo.
