Hi! I have a 50-gal main tank, but since some of my fish aren't invert safe and I love inverts, I was wondering if I could keep 2 pom pom crabs and 2 sexy shrimp in a 3 gallon tank. I have a 10 for my quarantine tank so if I needed to upgrade, I could. If I did the 10 gal I'd move my damsel in there bc she's a pain at times. Would this work? Ideally I hope it works in the 3 bc I would like to keep my hospital-10-gal, but if there absolutely isn't a way I could use the 10. I am very limited on space and funds, but if there is no way at all it will work, I'll probably do the 10. I know the damsel couldn't be in the 3, but a teacher and friends told me they would be fine as tank mates and would do well in a 3 gallon. Thank you, all.
