While at Dave's he showed me a nice shrimp hatchery with no bubbler. Went order it and was $30; sorry but that is way to expensive to hatch shrimp in my opinion. So went to the dollar store and picked up to food storage containers and 3 blue plastic cups. Had some leftover black spray paint and made this. Let me know what you think. Cost with paint was under $10 and I can make one more if I want.
