No I wouldn’t say it’s too crowded. For the tank size that it i think you’ve set it up fine.

But i would agree the minimum size should be around 40 gallons for a dwarf. So if you could upgrade that would be good. I find that sized tank too narrow really so you can’t set it up too well.

Also keep an eye on the wheel size - think it’s the 6.5” diameter one but dwarfs do better on an 8 inch one, so an upgrade is worth thinking about.

Edit - Should have added while he’s in this cage I’d fill the cage right up with bedding. At least 6-8 inches for a dwarf preferably more, so he can burrow.
