everytime I see a glass container I have to put something in it. I have a goldfish bowl. If I were to guess 1 1/2- 2 liters. Or 1/2-1gallon. Right now I have dwarf hair grass in it which I don't care 4. What can I put in it? Don't say mealworms, betta, superworms, maybe some kinda aquatic worm would be cool. I have a desktop lamp in it with a dimmer. With it off it's 61 with it on the lowest it's 70 highest it's 80degrees.any suggestions? Fish shrimp worms? Anything? Thx
