I have enjoyed the handful of shrimp in my two aquariums so much that I want to setup a small tank just for shrimp. Any advice on how to get started? I was thinking of a 5-gallon tank with some java moss and cholla wood. 1. Can I mix species? 2. How many shrimp do you need to start a small breeding operation? (for fun, not profit) 3. Do I need any special water treatment other than having a cycled tank? 4. Any other tips or advice? 5. I will probably just have shrimp in the tank, but are there any other fish that don't eat baby shrimp that would be compatible? Thank you!
