I started my 125 gallon in April. I started adding a few fish in march along with copepods. Shortly after, I noticed some we're scratching not bad, I kept them feed well and did frequent water changes and they got better. It came back. I caught the fish that we're scratching and did a FW dip and put them back in. Everything seemed to be ok for a while. Then all of a sudden fish were dying every day. I pulled all the rock out and caught the rest and put them into QTs. I was sure it was flukes, which I treated them for but continue to lose fish. I had a microscope and did a scraping and it was nothing I've seen before. I am now convinced it is a Copepod parasite infestation. It is now eating my coral.
Can anyone confirm, give advise?

Hard to tell from image but may be an isopod. If so, give fish a 5 min freshwater dip same temperature as display tank and it should fall off

So today, I noticed in the DT, there are a few coral that didn't look good, so I pulled them out and did a dip of Revive and look what came off of them! I took the coral out of the solution and left the parasite in the dish, and there's still some crawling after hours of being in the solution.

I have done that plus a hydrogen peroxide dip. They are eggs on everything and multiple that crazy. It's been very hars to control.

If there are eggs on everything, they would not be copepods eggs.

The female copepods carry their egg sacs with them until they hatch.

You are dealing with two different problems here, or you are miss IDing the eggs.

Again, a picture of these eggs or the fish would help

You posted in the chemistry forum instead though? Anyways, you should choose one to focus on, and ask the mods to delete the other one

Sorry , no - I meant post in the reef forum about copepods as a coral pest. The fish dying isn’t from copepods.

I went back and read the start of the original thread - I didn’t realize it then, but you posted on somebody else’s thread and I thought I was replying to the original poster, not a new person.

You need to read the post I made about dosing praziquantel, your fish have/had the symptom of flukes.

Copepods act like micropredators on fish - they bite the fish and cause minor damage, but I’ve never had them kill fish outright.

Jay, sorry for the confusion there.
I did a scraping on two different fish and dips and what i saw under the microscope was white bugs. They are visible to the eye and so are their eggs. So I'm very confused on how to treat the few fish I have left.

Can you post a video of the remaining fish? I've seen copepods parasites and copepod micro predators on fish, but I don't think I've ever had any fish die just from them alone.....

These are all over their bodies

From the article that I posted:

Insect Growth Regulators; Cyromazine and Diflubenzuron (Dimilin) are sometimes
used for the control of crustacean parasites in fish. Never apply these compounds in aquariums that house arthropod invertebrates. They only affect these parasites when they molt, so terminal molt adults are not harmed. This means that you must remove the adults through a dip process, while at the same time, dosing the exhibit to kill off all larval and sub-adult stages.


So - Dimilin would be your best option. You can buy this in the US from Amazon as "Dimilin-X".
