My friend is currently dealing with Crypto, and asked for help. His powder blue tang was infected when I got to his house - it was not completely covered, just on his fins and a couple on his body. I watched him eat and he was breathing normal and eyes were not clouded – My friend asked me to nurse his fish back to health for him. I Brought him home, acclimated him and dropped him in my display tank. I always feed with Garlic so I didn’t have to adjust for that. My Wrasse and cleaner shrimp went to work on him and now 5 days later he is Cryto free and a happy little camper. He will be going back to my friends tank in a few weeks once we know he is healthy again and his home is ready for him. I wanted to post this as I read all the time about “ich” and drastic measures like fresh water dips, quarantines and full tank treatments. Don’t get me wrong, if things are let go to a point than some of these methods become valid. In my opinion, for what its worth, Crypt on the fish is not the concern, the concern is what caused it in the first place. By placing this animal in a healthy environment, coupled with his health not being so debilitated as to give rise to a secondary infection cured the fish. Therefore, if you have Crypto you need to treat it like a nuisance algae and go after the cause more so than result. Safety first, I always have a broad spectrum antibiotic on hand incase of a secondary infection – this is the killer. Poor diet, poor water quality, fluctuations in water parameters, stray voltage, poorly matched tank inhabitants, excessive in-tank tinkering – these cause stress and weaken immune systems to the point of Crypto rearing its ugly head. Anyway, like I said – just my opinion that I wanted to share. Back to my friends tank, his issue was stray voltage. I had a cut on my finger that tingled when I put it in the water. We found his grounding probe completely coralline encrusted rendering it ineffective. A few scrapes later the stray voltage was gone. He still has two clown fish in his tank, if they stay healthy he will take his tang back in a few weeks…..a happy ending.
