my new brain

Also, mine seems to have 4 mouths! Is that normal or do they split?

4 mouths how? Like 4 circles of feeding tentacles or 4 holes where the food goes? And as far do they split as far as I know nobody knows 100% but there is speculation that they may but it would take an incredibly long time because of their thick stoney base. Also thinking about it there wouldnt be much of an advantage for them to asexually reproduce as they are not motile.

Yes they can have multiple feeding holes. I had one very similar to yours and it was HUGE!!! It had feeding tentacles always out searching for food. If your new to open brains dont be shocked if they uninflate suddenly. They do that time to time when expelling waste.

Yes there are 4 holes, guessing that's where the food goes. They are def holes though, not tentacles.
