A user on this forum by the name of Scottyhorse, gave me a great idea that I think everybody should know.
I have a 3g tank on my bedside table with a Betta in it. I didn't have a hood for it and the water was evaporating so I asked for tips.
Scottyhorse then replyed saying to go to Home Depot, cut a piece of plexiglass into the shape of the top of my tank, drill holes for air and light and place it on top! This genius idea is defiantly getting used by me and I had to share it!
