Moto Stingray trouble. Help please

[Gshock]

It's been almost a week of stable ph. I didn't feed the rays for a few days. Now they're back to pigging out. My larger females poop is white now. Parasites?

Possibly parasites, did you introduce anything new into the tank such as tankmates?

 

[grunzilla]

yes. But I run a big uv sterilizer on my tank.

yes. But I run a big uv sterilizer on my tank.

I doubt that will be helpful unless the UV takes in all the water in the tank prior to it making contact with the other fishes.

Once a parasite attaches itself to the fish, no UV can remove it since you are not passing the fishes though the the UV.

Yeah. I just figure the chances are less of passing parasites along. Plus, the new fish I added was a very healthy specimen from an experienced fish keeper. None of the other fish are showing signs of parasites.

Today the rays feces was a lot more solid. Still had some stringy white, but not nearly as bad as before. I'm gonna keep an eye for a few more days. If It doesnt let up I'm gonna separate it and treat with prazi pro, unless there's a safer parasite treatment for rays I don't know about.
