Hello, I've recently cycled my first 20 gallon tank. I originally had only a rubber lip pleco in there, and today I got 1 vampire shrimp and 5 pea puffers. I also added plenty of live plants to make sure there's plenty of cover in the tank. I talked a lot with the employees at my local fish shop, but would love any insight/tips for making sure the tank stays in good shape and everyone is happy. The main things I am concerned about are the filter flow (pea puffers wanting low, Vamp shrimp wanting high?) as well as the puffers potentially picking at the pleco or shrimp. Thanks in advance for any help!
