Shark and ray adding

[fishguy777]

Tough to say, I can’t clearly see any blanching that would indicate the presence of crustacean parasites. The issue could be flukes, leeches or turbellarian worms. You could try prazi - that would help against flukes. Leeches or turbellarians would require a formalin dip and then moving the fish to a new, parasite free tank, to allow any parasites in the tank to die from lack of a host.

if my other tanks aren’t adequate, what should I get to make it work? Also, how long would the tank have to be fallow?

Since the ray doesn’t have any major symptoms yet, I think you have time to try prazi. You can do that in your display tank. You dose it at 2.2 ppm with good aeration and no carbon. Then dose it a second time after 8 days. If that doesn’t help, you’ll have to try a formalin dip on the ray and move it to a new tank.

I found a nice aerator-gonna have it blow the bubbles through my wave maker. On the bottle of Prazi it only says milligram/liters, how do I convert to ppm?

PPM and milligrams/liter are equivalent. The typical dose is 2.2

Would the move be just the ray, or all my fish? Inverts too?

Only other tanks/spaces I have is a 65 that was previously exposed to copper and a 50 gallon tub.

Oof that would be a rough period. Petsmart has 40 gallons on sale, you could get a couple of those and put fish between those and your other tanks. If I remember right you have a lot of tangs and other high bioload fish?

Yeah, I think now might be the time to invest in a Rubbermaid tub, I have all the filtration and heating supplies on standby already

Hi jay, I’ve been treating tank with prazi for 4 days now. No observed improvement, he’s still eating good, would kanaplex+metroplex+searchum focus be worth a try?

If there was no improvement with the prazi then the issue isn’t an external fluke.

This may be a self-limiting parasite. These have multiple hosts in their life cycles, so they cannot reproduce in an aquarium. Are the spots getting worse or are they the same? If the latter, then you might want to wait it out.

The other option that I mentioned is risky - a 150 ppm one hour formalin dip with good aeration and move to a fresh tank.

I don’t see any call for kanamycin. Metro and focus? A big no on that - there is no indication that internal protozoans are involved here, plus you can’t just mix focus with medication, it must be dosed correctly - for metro, that is 1% in the food by weight. Then the challenge would be, how to get that into the ray?
