I can't find a size for this hara in the Cat-elog, but I have Hara jerdoni (or at least that is what they were sold to me as) in a tank with red cherry shrimp culls, and I've never noticed a drop in population to the point I worry. Should be fine, unless your fish is large enough to eat adults!
But if you tame me, then we shall need each other. To me, you will be unique in all the world. To you, I will be unique in all the world..... You become responsible, forever, for what you have tamed.
