I’m new and my family and I got ghost shrimp and one went white and I got super worried and googled why he’d be going white and found this forum and am so thankful for this!! It ended up being the copper sulphate in the fish food!! I immediately quarantined them in 3/4 fresh water and have been changing half every two days and I’m glad I caught it cuz he’s doing so much better! We got new food for them too of course! Forever grateful for Fish Lore and all of you that contribute to it!! So happy our little shrimp is still alive and doing good again!
