Alright SO..
A few weeks ago I realized my refractometer had gone out of calibration and my tank was quite low on salinity. It definitely angered my torch coral but it seemed to perk up over the last few weeks once I fixed it. Not 100% though.
Anyhow, last night I was looking at the base of another torch in the tank and saw what looked like a spot of coraline algae (I have a lot popping up), but it squirmed! It was a flatworm. I pulled the torch and dipped it. The worm writhed around a little bit didn’t die. I sucked it up into a syringe and tossed it. Also saw its eggs, so I thoroughly scraped them off and rinsed the torch and put it back.
Next, I examined my other torch- and saw another. And another. I managed to suck them up and remove them too. But I can’t see and reach the eggs at the same time.
I dosed prazipro and then I’ll dose again in a few days when the eggs are liable to have hatched but before they lay more. Hopefully I can wipe them out this way.
Anyhow, I also noticed this brownish looking area on the base of my green torch. I suspect the flatworms are hurting/eating the torch so I’m not surprised to see any damage but is this the dreaded brown jelly? Or tissue death? Or something else? The base is usually a really pretty white, so I’m very concerned.
Anyone know how best to handle all this? Any thoughts are appreciated. Thanks.
