I finally bought some new yellows for my picky females who won't breed with the males I have. Of course I also had to buy some fires for my females too, and a couple of blues + pumpkins since they had some. ? It seems I always get so many more females than males, so I had to even out the numbers more.
One of the fires I bought had that light line down its back, meaning it was just about to moult. I was hoping acclimating & moving to a new tank would trigger the water parameter change it needed, but apparently I was wrong and it died overnight. Sucks.
This made me wonder if there isn't a way to treat a shrimp who has a failed moult happen and triage to save it? With birds who are egg bound you give them liquid calcium to immediately fix the issue & save their life. Is a failed moult a calcium deficiency? Or maybe all nutrient deficiency? So potentially triaging them with nutrient-rich water would stop the problem? Maybe putting them in a quarantine tank and add a drip line with blackwater.. I may be totally off but there should be some last-minute fix for once you notice the signs (the light-colored line, hiding for a molt, struggling/wriggling but no moult detaching).
It never happens in my tank, but whenever I purchase new shrimp there's a chance one or more will be right in the middle of their moult. I am always buying new shrimp these days so I want to have some way to stop it.
