I have NO idea! What about just a water plant aquarium, just plant floating and growing, no fish?
A lot of people really love planted aquariums with nothing else in them. I find them boring personally
. Maybe look into a 10 gallon planted aquarium with a school of 10 or so chili rasboras?
I don't know if it's my coping mechanism but it keeps me sane. People that can't laugh scare me.
Now I'm laughing and can't stop!
