Ick/velvet only at night?

[bcournoyer5]

For the past two nights, I have come home to ick/velvet on all of my fish (12 total 6 tangs). Last night I treated copper and I woke up this morning with no presence of anything, besides a little bit on the blue tang. However when I got home tonight, it was back worse than the night before. I did leave the lights on longer than usual this past week since I’ve been getting home late. Is it because of the lights? I don’t see how in the mornings they are ok and at night they are not. Any help would be greatly appreciated

For real reasons unknown, theronts are released mostly in night time. some suggest this strategy increases the chance for theronts to find a host, as many fish may be resting or closer to substrate during night time.

You can educate yourself on the life cycle of ick here. Google for the life cycle of velvet. Velvet moves much faster, btw, than ich.

Can you post some pictures?
What are you running on your tank (carbon, GFO, etc.)? It could be that the copper you added helped, but then was pulled out of the water, allowing the parasite to regroup... I've never heard of things moving that fast in terms of copper/carbon, but I guess it may be possible...
Is this a QT tank? Or a FOWLR? Or did you dose copper into your reef tank? :-O

This is a fowlr tank

This is the best pictures I can get and these pictures definitely don’t do it justice

Also, not one fish is scratching on the rocks or substrate. All are acting normal and are eating perfectly

Puffer also has it on it’s fins, most fish in tank have that too

I don't see any signs of ick, but it is hard to tell. It's always hard to get pics of fish, isn't it? :-S

Are you sure what you are seeing isn't just sand dust and such from the fish sleeping at night?

Positive, those pictures are from right now

Honestly from those pics fish look clean. Also as night time most tangs will show white pigments if startled. You think it might be that?

No, I he pictures do not do it justice, the camera isn’t picking up the spots

I see spots on the blue tang - and the fins of the puffer - but the pictures of the clown and the other aren't close enough.

Did you qt the fish before placing in your tank?
Blue tang is almost 100% known to be a carrier of ich in ny experience.
I would highly recommend to get a qt setup and run either hyposalinity or copper or cp

The clowns are good, they are all set. Just the powder Blue, puffer, and blue tang have it right now. All the other fish get it only at night around 10pm just before lights out, and in the morning, everyone is fine except for the powder Blue, Blue, and puffer. Every morning things get better and at night it’s terribel

If one or 2 fish have ich whole tank has it. Treat all fish and leave main tank fallow for 10-12 weeks.

its also possible that they are partially or totally immune - though thats risky.

The reason I've heard theronts are released at night is there is more of a chance of contact with the fish (who are usually 'holed up' somewhere and not moving. It maximizes the chance of contact.

So if I treat me tank with copper, it should go away?

@bcournoyer5 It seems that you have multiple threads created in the past week or so indicating various issues with most of your fishes. In those threads, it sounds like there may be some misunderstanding of treatments like adding copper and your fish being cured of ich/velvet. Could you please post a full tank shot of your aquarium? Please also include a full list of the fishes in the tank and an estimate of when they were introduced. Could you describe any quarantining/acclimation process that the fish have gone through? Basically whatever you did with the fish between your fish store and the display tank. I'd like to get an accurate depiction of the fish in the tank, the symptoms each is exhibiting, and then we can discuss the steps necessary to get all of your fish healthy and happy. Thanks!

PS: In other posts, you've mentioned the fish exhibiting symptoms of ich which "always goes away after a little copper dosed in the tank" and that you "dosed the tank again a few minutes ago with the rest of the copper medication". I'm not sure how much copper has been dosed at this point but it sounds like a possibility that too much copper has been added to the tank. Also, I would never add copper to tank that has a puffer in it. I'm not sure if the puffer is in the same tank as the tangs but if you provide the information I requested above, we'll all get a better idea of the situation.
