Hello folks, Posting a semi-update / question regarding my tank. Overall I would say that it is doing well, and I haven't seen any signs of the tiny bugs inside molted shells. But, as I've complained about before, there seems to be an age demographics problem. It kind of resembles a third-world nation with a vast majority of young shrimps and only a few village elders. Just using very basic statistics, if I assume that the shrimp are only dying of old age, and that shrimp reach full size at about the half-way point in their life, then about half my shrimp should be full size, right? Something seems to be taking out lots of the shrimp along the way. I can only track a few of the shrimp since otherwise they're rather indistinct. But there was this one group of 6 Golden bee that I started tracking since early 2024 which I referred to as the "Big 6". After reaching full size, they started going one by one, before the 1.5yr life expectancy. One day they would be fine - very active and at the prime of their life, and then suddenly they sit down and start talking about C-beams at Tannhauser Gate. (Blade Runner reference) Sometimes they still had stuff in their digestive tract when they suddenly shut down. (Not the one week's worth of staring off into the sunset like some of the other old shrimps) This went on until the last few months, where it's now only been the Big 2. And out of all the other younger Golden Bee, none have managed to make it to "big" size. I wonder if something is happening, like a shrimp will get randomly poisoned by something in the substrate, or if it's because the tank is overpopulated and shrimp get attacked and eaten when molting. Random bonus content: Here's a rare distinct shrimp that I tracked from birth all the way into old age. Easy to tell because she had a clear transparent head. (I called her "Clear Head blue bolt" This gal lived for around 1.5 years, so I suppose one of the few that made it all the way.

I know it's a bit quiet here, as it seems most forum traffic has moved onto places like Facebook and Reddit, where people like to post for "likes" or other accolades. Anyway, I hope to see pictures again of your mixed shrimp.
