You just need to block off the filter inlet, so that shrimps won't be sucked to their deaths.
Sponge, foam or stainless steel mesh will work fine.
Do read up on maintaining the correct water parameters, and the tools necessary to do so. Check out the Water Parameters subforum.
Hi I'm an animal enthusiast with many frogs snakes and arachnids but it's my first attempt at caring for cherry shrimp..i researched with my girlfriend quite a bit and already set up a planted tank in a nano 2.6gallon aquarium. It will be cycling and until then I just wanted some feedback on how it looks and what y'all think about it? Thankyou ~
