Is it Crypto (Marine ich)

Reefing newb
:frustrat: I have had my Saltwater tank up and running for about 10 months. After 2 months of cycling I added the first fish. I didnt quarantine these fish. I was new to marine fish and didnt know any better. One of the had ich and it killed both of them. I bought some reef safe ich treatment and followed the directions on it. Then we decided to buy more fish. Again they got ich (except 2 percula clownfish) even after 4 weeks of quarantine, within days of being put in the display tank. So then I read everything availiable about marine ick. I removed the 2 percula clownfish which did not show any signs of ich and qaurantine them with copper for 6 weeks and then 2 weeks with no copper for a total of 8 weeks. The tank only had a cleaner shrimp, horshoe crab and a turbo snail. Nothing was added during this 8 weeks to try and finally kill off the marine ich. About 9 weeks ago i placed the 2 clownfish back in the display tank. After being in the display tank for 2 weeks they looked fine, so I bought a black and white Heniochus. When I bought it, it had Lymphocystis (the lfs store told me what it was and they had had the fish for about a week and it was eating fine. They told me it was a virus and it would disappear after a week or so). They were big white cottony looking spot on its dorsal fin. After the trouble with ich, I now have a permenant qaurantine tank. I brought the fish home and after a week in the qt it had no Lymphocystis visible. I left the fish in the quarantine tank for another 6 weeks. The fish was looking healthy no white spots and active and eating well. I moved it to the display tank about 4 days ago. Now there are some white spots showing up on the dorsal fin again. They are small and just a few, about the size of a ball point pen tip. I have read that Lymphocystis can reappear on a fish especially after moving it because of the stress. Is this true or could it some how be ich again. My water parameters are as follows, ph 8.3 - 8.4, sg 1.024, no nitrites, no ammonia, nitrate 40ppm( I know it is a little high), Alkalinity about 3 meq/l. It is a FOWLR tank 40 gallons. I cant get a good picture of the fish to post. Any advice would be appreciated. Thanks!
 
Welcome to the site, Duke! Sorry to hear of your sick fish woes.

Unfortunately, from what I read about lymph, there's no real cure, but for the most part, a fish can fight it off....the problem happens when it starts growing around their gills and mouths, for obvious reasons. Stress usually causes a fish to show signs again, so the move into the dt would cause it. If your tank IS a 38g, it looks like the tank's size might be contributing to the stress, since they usually do better in 50g or more. Plus I think they are schooling fish, so being alone might be another factor.
 
Did you treat the butterfly with anything while it was in quarantine? If you didn't treat it with anything and just kept watch over it for those weeks, it could very well have brought ich back into your tank. You must not only quarantine, but treat all new additions with either copper or hypo if you want to prevent ich from being introduced into your tank.
