Thank you for the helpful response.
At the moment space is a concern so something small is the only option for right now unfortunately. I will definitely start small with 5 and then let the build up their population. Hopefully I will be able to give them away locally when I get too many as I dont have the heart to cull anything. The pH in my tank now is 6.2 with pressurized co2 and ecocomplete. I can double check but that is what I got for kH as I dont have a gH test.
Does anyone have suggestions on must have additives or foods? I have been reading alot but there are so many brands and so many individual products marketed for shrimp its hard to really tell what you need and what you dont need.
