I've gotten pretty good at knowing when my shrimp are going to molt. Couple of signs I watch for is the little back legs being held straight down and the front legs (or a pair of the fronts anyway) stretching straight forward in front of the head. Saw one of my amanos doing this and grabbed the phone. This hasn't been edited, I really did time it this well. The video JUST got uploaded so the quality should improve in a bit. Enjoy!
Yeah...a really tight one. LOL! I swear the first time I saw the back legs straight down like that I just knew the shrimp was dying...then it molted. So I started watching them more closely and it really does seem to be a common pattern just prior to molting. But it can go on for a good 10-15 minutes or so...it's like the stretch to get the exoskeleton loosened up
I had one go through a bad molt yesterday...the OEBT in the video...you can see her little back legs down...they are sort of stuck in that position right now. From what I can tell it came off her head, then there was a section left in the middle, then a section that came off, then the molt on the tail was left. I was away when she molted yesterday morning. I've kept an eagle eye on her and she is taking some of her front legs and running it down her sides, trying to pinch and grab the molt to pull it off. She has most of it off that was left on the body, it's in shreds now kind of floating about. She keeps tucking her tail trying to pull off what's left on that but it's not budging. Haven't had a bad molt in this tank and all params checked out fine so I think it was just a fluke thing. But I'm hoping she pulls through the next molt...only got 3 OEBTs dangit.
