I started a 3 gallon planted bowl a few weeks ago for something to do with my leftover hardscape materials and plant cuttings. Since I set it up and got it growing, my mother has been asking me questions about keeping shrimp. (She got one of those little self contained shrimp ecosystems for Christmas and loves them, so she wants to move up to something she can actually interact with outside of being The Scary Hand that turns their world every few days.) I'm planning on giving her this set up and helping her get it ready for a couple of shrimp. I think I've got most angles covered but there is one problem: a lid. The top opening is a little less than 10 inches across, so I was thinking of using a 10 inch embroidery hoop strung with mosquito netting. I need something that light will penetrate for the plants. Shrimp Bowl by Briggs posted Apr 9, 2017 at 11:57 PM Am I overthinking this? Should I just tell her to keep the water level lower and hope they don't crawl up the air tubing? I'd love to hear from anyone who's kept shrimp in large bowls or jars. How likely are they to make a run for it? Do you think the curved sides of the bowl will slow them down at all?
