I'm getting a twenty gallon and just wondering if I could keep one or two vampire shrimp
Vampire shrimp are filter feeders, despite their name, so you'll need pretty good circulation. Extra circulation will be appreciated
How many shrimp do you need I know they're social
"Vampire Shrimp need a decent amount of water volume to feed, so the bigger the better. A 20 gallon aquarium can be a good tank size to start with. Of the 20 gallon tanks, a 20 gallon long tank can be a good choice because the dimensions are 30″ x 12″ x 12″. A 30 inch length means there is a decent amount of aquarium bottom to walk on. The 12 inch height means it isn’t very hard to keep the water current moving quickly throughout the tank." http://www.aquariumcarebasics.com/freshwater-shrimp/vampire-shrimp/
If you add a submersible pump, you cab make a hillstream tank with some small, peaceful fish. I thibk that'd be pretty cool, IMO
