My 1 1/2 gallon shrimp jar started with 5 brown Neocaridina shrimp that were culls from a local breeder. Now there are several red and brown younger shrimp. Looks like there's a new batch.
1 1/2 gallon jar, black gravel over sifted organic potting soil. No heater. No filter other than plants. 1 air stone. Planted with dwarf sagittaria and cardamine lyrata.
