Des nouvelles de mon petit aquarium sympa. ^^

Après quelques péripéties (et la perte de quelques danios margaritarus –m'en reste 2 d'avant– et quelques crevettes), mon aquarium est de nouveau en forme, bien propre et prospère ! 🎉
Et j'ai quelques nouveaux danios mais tout bébés petits et gris pour le moment. ^^

Footage of the #shrimp that came with the #aquarium gorging itself on some feed (possibly the first proper meal it got in a long time - it really went ham on those pellets)
I didn’t have much interest in shrimp before but they’re growing on me.
Based on my research this is an amano shrimp aka Yamato shrimp aka #Caridina multidentata, and probably a lady. The next step is to get her some housemates as they shouldn’t be kept alone.
“There’s such a thing as ornamental shrimp?” This is the typical response of family and friends when I speak to them about my recent hobby of keeping ornamental shrimp. Believe it or not, there is growing interest around the world about breeding and keeping these little freshwater critters as pets. In some countries, their popularity even rival traditional fish keeping! What once used to be considered another algae eater in tanks has quickly become an object of interest for aquarium enthusiasts, given their behavior, varieties, and breeding possibilities. They are marvelous to look at, and as such are wonderful subjects to photograph.
Aquarium Plotter Shows Sisyphish’s Submerged Sand Stripes
Sisyphus is cursed to roll a boulder up a hill for eternity. Pet fish generally content themselves to swimming the same lap over and over in a glass tank. Perpetuity can be soothing, so long as you're not shouldering a boulder.
[Zach Frew] wants to integrate and automate the boulder on a smaller scale and one that can benefit his aquarium full of colorful Taiwanese bee shrimp. Instead of an inert rock and a Greek, Sisy phish uses a magnet and servo motors connected to a microcontroller to draw Spirograph-style shapes in the tank's sand.
There are a couple of gears beneath the tank to trace the geometric patterns but they're clear of any water. One gear rotates about the center of the cylindrical tank while the other holds a magnet and adjusts the distance from the center. Pilots, and select nerds, will recognize this as rho-theta positioning. Despite the uncommon coordinate system, the circular plotter accepts G-code. We love when math gets turned into gorgeous designs, and shrimp love when those tasty microbes get shaken from their gravelly hiding places.
We adore the dry sand plotters that came before, and Sisyphus himself appeared in a LEGO format that made us question our proficiency with the blocks.
