WOAH. To weird. My nem is completely bonkers.
Ill try to time line it the best i can
It started twisting off tenicles, id find 3 a day sometimes... probley 10 all together
Then it started wondering after being in one spot for 8 months, it wondered for 3 weeks. (started 2 days b4 xmas when i was out of town, bf had a heartattack and slept next to the tank for fear of powerhead chopping)
It was fine thru xmas but it did end up encountering my skimmer pump. I had it covered with needlepoint plastic and nothing was damaged at all.
After three weeks it crawled to the very tippy top of the rock closest to the light. It has now been there on the top rock for almost 4 weeks. It is now growing pink tips out of the sides of its tenicles, then twisting the top of the old tenicles off so the new pink tip is now the top.
It still catch a tenicle a little twisted but it doesent twist them off.
Where the tenicles were twisted off at the very bottom at the disk, a new tenicle sprouted within a day.
The light was replaced a month before it started the twisting. It was replaced with the exact same bulb that I took out, and the old bulb was only 5 1/2 months old (hamilton 14k)
No perimeters went suddenly out of wack or anything, they have been really stable throughout this whole weirdness.
My nitrates were maybe 15 when I started testing everything I could. they are now between 2-4 agian.
I cant help you in any way. It really stressed me out. But all I can think of is it was regenerating tenicles or somthing. I dont think it was a flow issue at all......
Mine never ate its own tenicles.. although it would suck on one sometimes.. like it got stuck when she closed her mouth after a meal.
I feed my nems every third day silverslide piece
