So I got a Blue Hippo Tang the other day. I acclimated for 2 hours by drip line. All was fine the fish is social towards my Tomato Clowns and eating flake and frozen foods. Today I noticed a spec that looks like Ich. I do not have a heater they are on order now of course but can I add anything else that won't effect macro algae and the pods that are living in the macro?
