Another Question

also how do most plecos mouths work?

Imagine a cross between a vacum cleaner and a power sander.

They latch on with their sucker mouth and have tiny teeth on their jaws that rasp away at anything edible which they then eat.

So they cant swallow large items, but they will rasp away at anything edible and just wear it down.

sounds like they would be messy eaters if they weren't in water, thank you.

So a pleco cruises around until it sees / smells something tasty and then sucks on to it and then rasps away edible material until the area is spotless of food.
