Flukes black ich?

[N11morales]

Welp not qting caught up to me in this new tank.

I noticed brown spots on a rabbitfish I just added.

Also white round spots on copperband


Any idea what this is? I’m assuming flukes or black ich?

Very hard to get better pictures

Tanks fairly knew no coral yet. There anything I can dose into the DT? I have too many fish to take out for a QT. No room for that large of a system.


Tank is a waterbox 290.6.

Roughly 200G display.

The rabbitfish spots aren’t just spots. They have stringy substance coming off it. The stringy part moves with the flow but the “spots” itself don’t move at all on the body

This does appear to be black ich which are turbellarian worms and likely the Paravortex version which are smaller and appear as grains of black spots and can have the stringy appearance you describe. These worms have a single host life cycle producing several juveniles which can last up to 30 days but rarely do. Best is to treat with Praziquantel better known as prazi pro for two 8 day intervals with a water change on day 9.
other option is formalin based medication such as quick cure or ruby Rally Pro starting with a bath for 45 minutes followed by treatment
Do note that Prazi will lower both oxygen and appetite, so an airstone is recommended for added aeration and monitor water quality during treatment with a reliable test kit, For temporary relief, you can do a 5 min freshwater dip the same temp as display tank. Use tap water in lieu of RODI

Okay Ty for the help! Prazi pro is okay to use in DT right? I don’t have any coral and small amount of inverts.

I’ll try to catch for a freshwater dip to help. Prazipro is ordered but won’t get here until Friday.

Yes and to be safe, dose at 85% of recommended dosage

At least three fish - the rabbitfish, copperband and the convict tang are thin. This may be from being starved through the supply chain , but if you've had them for awhile, you need to feed them more.

Praziquantel does NOT work well against turbellarian worms. The way prazi works is that it causes flukes to become catatonic for a bit and drop off of the fish, and then, they cannot return. Turbellarian worms live in cysts, so they don't fall off of the fish when dosed with prazi. However, many infections of this disease are "self-limiting" in that unlike ich and velvet, black ich can go away on its own. That can make it seem like praziquantel was effective, when actually it was just time. Formalin dips are the best treatment for this, but tough to do.

I can't see if the fish have regular ich or not. They may well have flukes though. I don't see any invertebrates in the images - if you can remove any inverts, you can run the tank under hyposalinity. that helps with black ich, will cure regular ich and will cure flukes.

Hyposalinity

Hyposalinity Jay Hemdal 2024 This term refers to a long-term bath treatment for marine fishes in which the salt content of the water is lowered and held below the point that certain parasites can survive. The salt level reached, and the time of the treatment are the two variables...

I have 3 shrimps that’s it.

Rabbit, copperband, and convict have been in the tank a week.

I finally got the copperband eating. Others are eating a lot as well.

Feeding 3 times a day + nori


I will try to catch the shrimp today and then try hyposalinity.

Should I slowly drop the salinity?

 

[N11morales]

If it is flukes and black ich.

Can I move my shrimp to my other tank? It won’t transfer through shrimp will it?

My 75G is disease free far as I know. Tanks up for 4 years now 0 problems with my fish.

Yes - there is a risk that moving the shrimp to a new tank will transfer the disease with them. You can reduce, but not eliminate that, by acclimating the shrimp over, but don't allow ANY water to get into the new tank. then, transfer the shrimp to a container of new tank water for an hour or so (with some aeration) and then move them over without letting any of that water to get into the new tank. You'll need to weigh the risks and benefits of doing that, but since there is no real way to gauge the risk, you may need to make a decision to either risk the fish in the 75, or put the shrimp in another small tank or vessel and risk losing them.

You should get the first tank to hyposalinity within 3 days, as outlined in the post.

Freshwater dip I agree with. I am reluctant to recommend Hypo as these flatworms which make up the dots do respond to prazi and Hypo with certain fish is a risk but does also kill all stages of this flatworm

I'm going to try Prazi first and if that doesn't work I will slowly drop to attempt hypo
