This is the tank now I added some bigger pieces of woodA puffer is not like some of the big cichlids.
For a lot of the big cichlids they just want to defend a log all day so that is all they need.
The puffer is more of a thinking fish. It wants to interact with the environment and look for new things. Think more like building a tank for a kitten. You need to make different areas for it to explore so it has fun. I would stack rocks to make various holes big enough to swim through and use driftwood to make something elaborate for it to hunt in.
Plus the tank will look better for your eyes as well.

When I drop food in of pretty much any kind he usually doesn’t eat it for a while. Only pellets he’ll eat immediately sometimes but not with a strong reactionYeah here’s another photo. He just continuously surfs in that corner or lays on the bottomView attachment 1575517
