I think he's fine with what he has now. There is A LOT of plants in there. I had to stop fertilizing them for a few days b/c they are getting so big taking up more than 1/2 the tank
sounds like it's time to get another tank to plant the overgrowth in! and as a bonus, you've got a home for a new betta!
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
