I have a one gallon tank with a betta i had for about 9 months, it has an undergravel filter and I was wondering if a small plastic plant or any other decor would be good if its happy with just an empty tank
I would say he'd probably enjoy it. It would give him something to play in, hide in or even nap in. Just a little sensory stimulation for him plus it would add more "oomph" to the humans looking at it!
