Ok...we bought one of those 2.99 5 1/2 gallon all-glass jobbies from the pet store. We have a cheap heater and an airstone in there, and an aquaclear 150.
We keep the water at 76 degrees, 1.023, ph 8.2.
The bottom of the tank has a plastic sheeting with slots in it. We feed artemia cysts (available right next to the brine shrimp eggs at the LFS) and drop in a few thera-a pellets as well.
We added 20 shrimp at first, then another 20 a month later. There is also a big piece of live rock that sits in the middle of the tank.
After about 2 months, we noticed little tiny shrimp congegating underneath the plastic sheeting. (You can get this stuff at any LFS, its made for undergravel filters to support the substrate).
All we do is lift the corner of the sheeting, and use a brine shrimp net, you usually catch 30-40 of the babies in one scoop.
Anything else?
