Sorry to hear of your struggles
I'd need a better picture to be sure, it looks to be something secondary to velvet.
What other fish do you have?
Keeping expert level fish such as a Moorish idol is probably going to prove difficult without QT. They have about zero resistance to parasites and other ailments, they are also finicky eaters with super high metabolism.
Can you upload some pics under full white light? Does he have a dusty appearance?
There are many great resources in the "Sticky" threads atop this section of the forum in regards to QT if you are interested.
I got him last Thursday and he was fine. It’s one of my favorites in the tank. I noticed this a day or two ago. It’s all over it’s body on both sides.Now it’s worse, swimming erratically. All of my other fish are fine. No I don’t quarantine. I don’t have the knowledge too. I’ve had this tank going since Mar 18.I love my tank, but dang this hobby is killing me and my fish. I’m about ready to give up. Can be really upsetting at times. I’ve never had such a hard time keeping animals. I saw two Idols at a LFS that looked like this and I declined. Actually the owner said he wouldn’t sell them to me the way they looked. Now mine looks exactly the same way. I’m tired of fish dying, wasting money and time maintaining this tank.
It really is disheartening. Don't get me wrong they had some beautiful fish there. I saw a lightening maroon that was over 6 inches long, just magnificent. There were storm clowns there almost 4 inches long. But most of them had ich. The store had just got some type of wrasse, I think lyre tail somethings and about 3 of them were actively dying when I was there. I just think of the amount of fish that die vs the amount of fish that are sold and stay healthy and that saddens me. Qt and treatment should be done by default in lfs imo
Cool set up!Guys lets keep this thread heading in the right directions. I doubt any of us didnt make a mistake or kill a fish. I run 5 QTs and take the time researchibg diseases but still sometimes some fish just wont make it. And i did have velvet slip through quarantine one time. Hers a small qt i run in a small appartment. Its hidden in a small cabinet with a small planted tank on top its only a 20 G with a simple hang on the back and a skimmer. One rock and a small cup of sand for wrasses as well as couple small pipes for hiding places and an ammonia check badge . Reading about diseases and playing fish Dr can be challenging and interesting.
This. Many of those on "the other forum" are much harsher on people for not doing QT. The people on R2R are nicer, and willing to help you if help is what you seek. If a disease identification is all you wished for, that's fine. But if you do want suggestions for how to prevent this from happening again, the suggestions you get will be honest. No one is judging you, and certainly no one is making you do anything. Many of us have been in your exact predicament before, and changing our ways to the "QT life" has been a game changer. This is why we advocate it. And yes, many of us state it how we see it. I agree that it's none of anyone's business why you cannot accommodate a QT system, but if that is the case, you should only keep fish that are very resistant to parasites (not the moorish idol). Otherwise, the results you have experienced are likely to repeat.
Give it time. Some fish can build a resistance but now with a host so vulnerable as an idol, they will be growing exponentially. They are doing serious damage to the gills of the fish. By the time you see the spots/discoloring/swimming in to powerheads/cryptic behavior/hiding from light/foggy eyes -- the gills will likely be too far gone.
Velvet won't always wipe a tank if healthy fish out in 48hrs.
