I believe my pistol shrimp has ick but i know my flame angle has ick and i have been treating the tank for 4 days now with fishvet that is safe with invertebrates. It says on the bottle its coppper and malache free. My bigest probblem is that the pistol shrimp has got ick bad and i really have no clue what to do to help him if this fails to work. My mother sugested a fresh water dip for about two mins for the angle but i cant find any info if this safe for the pistol shrimp. What else can i do for my pistol shimp? Any help will be greatly appreciated.
