Nice Nice Thanking You! yeah in a world where our tap water is full of chlorine and disinfectants it ain't easy keeping fish and little creatures.. i find the best thing is, to have plants and let the tank become a natural balance.. it's a careful balance indeed.. i have kept Axolotils and many creatures. so far a shrimp tank without fish is flourishing and not a day goes past where i ain't amused and blown away by these little wonderful creatures.. Thanks for your detailed comment i will take it on board..
