really, they could hang around all day...
I noticed that the cherry shrimp love plants. They love to hang from water lettuce. They also love to eat. I add Equilibrium to my water so that it's not quite as soft.
Let me know if you'd like some water lettuce for your shrimp. Water lettuce multiplies even faster than shrimp and endlers!
If you are going for EASY, don't go for Amano...im planning to get a new tank for shrimps this September, can someone teach me how to breed shrimp? preferably cherry shrimp
