sarah Posted February 11, 2016 Report Posted February 11, 2016 How long should it take a shrimp to molt, from the time the shell behind the carapace opens up? Is it minutes. hours, days? I just noticed one of my PFR adults got caught up in the outflow from my HOB filter, and it was so immobile that I thought it was dead. It landed on a leaf, and has not moved much in the last few minutes since. It's not dead, but it does have that gap, and the sides of the carapace seem to be flared a bit (can see in last photo)... so I think she may be trying to molt. Quote
35ppt Posted February 11, 2016 Report Posted February 11, 2016 I have seen them for a day, maybe more? with the shell crack. I think when you see them with the crack and they seem like they cannot move well, that's when the negative outcome happens. The one time I was lucky enough to witness a molt in action, it was just a few mintues from when I saw it 'fall' to the bottom, to when it emerged. Just lost one last night to a failed molt (no crack when I found him immobile, tho) I imagine water params have an effect on time to complete a molt, as well as perhaps size and maturity of shrimp. sarah 1 Quote
sarah Posted February 11, 2016 Author Report Posted February 11, 2016 Thanks for your input. I can't find her now. She is not in the same place, so maybe she is hiding out to molt. I hope so! Quote
35ppt Posted February 11, 2016 Report Posted February 11, 2016 Hoping for the best. I had 2 losses yesterday/today; one got past my sponge prefilter somehow. sarah 1 Quote

sarah Posted February 17, 2016 Author Report Posted February 17, 2016 Looks like I've got another one Unless perhaps it's the same one further along. Eating and behaving normally, but look at all those cracks... Quote
Soothing Shrimp Posted February 17, 2016 Report Posted February 17, 2016 You may have mentioned this already, but what is your gh? Quote
californiashrimp Posted February 17, 2016 Report Posted February 17, 2016 I'm not really sure how long it takes from crack to molt. But, I have seen mine kick the shell off and that takes maybe 2 seconds. sarah 1 Quote
Soothing Shrimp Posted February 17, 2016 Report Posted February 17, 2016 10 is not that bad for neos. I keep between 6-9 myself. However, having said that, if the neo strain you have has been brought up in low gh, they may not be used to the higher gh, and have trouble molting. sarah 1 Quote
sarah Posted February 17, 2016 Author Report Posted February 17, 2016 So the high GH will make getting out of their shell more difficult? Quote
sarah Posted February 17, 2016 Author Report Posted February 17, 2016 My TDS is also up around 300 in between top-ups, so I am going to try to get that down as well. Quote
nuri Posted February 17, 2016 Report Posted February 17, 2016 It is normal to lose once in a while a shrimp due to molting fault. But damn she's in bad condition. Btw: gh shouldn't be a problem,it aint high enough to harm. sarah 1 Quote
sarah Posted February 18, 2016 Author Report Posted February 18, 2016 Still alive. Still un-molted Quote
Shrimple minded Posted February 18, 2016 Report Posted February 18, 2016 That shrimp is going to explode..........you're going to hear a loud "POP" and turn around to see a lobster in your tank. sarah 1 Quote
