I found a couple of these cool antique 5 gal. distilled water storage jugs and would like to turn 1 into a planted shrimp tank. I'd like to have shrimp that will reproduce and keep a sustained population without having to buy more. I know of the cherry red shrimp that will reproduce in completely FW, but I'd also like some variety, so are there other species, or even just other color variations of the same species as the cherry reds available?
