I've been keeping shrimp for a few years now and these Jade Green #shrimp are my favorite variety.
Hardy, long-lived, and beautiful--love these little guys.

The tank is looking good. The moneywort plants haven't grown much, but everything else has, and I think there is enough foliage at this point where I can reintroduce some shrimp.

It has also been a useful excuse to revise some Bayesian filtering. I am not a probabilist in my day job.

with r the net accumulation rate and T the nitrate concentration of the tap water.

This is the same mathematics as the “nearly constant velocity” model used in target tracking: N takes the role of position and r of velocity.

Tap-water nitrate T is modelled separately as a slowly varying Gaussian random walk. That is an assumption, but a more plausible one than treating the supply as perfectly constant.

I haven't posted about my fish tank in a while, but here's how it's going since the last time I posted a photo. The plants are definitely coming along. It is still on a filter, but I'm just not home enough to babysit it through the transition period, so it stays for now.
