I just did the major obligatory tank clean. I still have a few with kinks but it's strange. The kink doesn't involve the top spine line. That is straight. It's just the tail itself. I've had no fatalities and no more have kinked. Strangely only my dark tads were affected, none of the albino. All of the kinks are well past the pelvic point so I have hope they will develop normally. They are approaching three inches and starting to move their legs autonomously.

I'm sorry I couldn't upload pics, it just wouldn't work.
