Marimo balls just arrived! They’re smaller than I thought they’d be, but they look healthy and cute rolling around the tank.

Snapping shrimp close their claws so quickly, they create shock waves. This video reveals how they do it
Less than 10 centimeters long, the few dozen species of snapping shrimp may not look like formidable foes. But their lightning-fast claws close so quickly that they make sounds louder than a gunshot, and create shock waves in the water that stun fish, worms, and other prey. But the evolutionary steps from simple pinching to ultrafast snapping were a mystery to scientists. Now, a team of biologists has closely examined the claw anatomies of 114 species of shrimp, including about a dozen known snapping species. As they report in Current Biology, they found two new types of claw joints heretofore unknown to science. The first was a simple slip joint—common in many pocket knives—in which a tiny ridge helps keep the claw open until enough pressure snaps it closed. This allows the claw to close a bit faster than usual. The second was an even further modified version called a cocking slip joint, where the ridge fully cocks the claw open. That allows snapping shrimp to build up incredible tension in the claw’s muscles before a secondary muscle movement releases it, slamming it shut at ultrafast speeds and generating a shock wave.
Check out this cool video! My shrimp, Mario, is a pistol shrimp.

I never expected it would get this popular! It makes me so happy that I’m able to inspire and introduce so many people to these wonderful animals. It’s so nice meeting others both in the hobby and out, being able to offer advice, make friends, and just talk about these animals.
Something I feel I’m responsible to say though, as several people are getting into the reef hobby after viewing my blog – do your research! I know it’s exciting and you want to jump right in, but please, please learn about the fish, corals, or inverts you intend to keep. Take a week or so, read up, look at the costs and needs of the animal. Not only could you hurt them if you don’t, but MANY of the animals in this hobby can hurt YOU!
And start off with the easy to keep ones. Work your way up!
I love so much seeing people get into keeping these critters, so if you need advice or suggestions – I’m here! I’d love to help!
So with that, thank you all so, so much for this community and your support!!! <3
She’s so tame
The pet store in town has this yellow tang!!! He is without a tail!!! He was still swimming around just fine. Apparently the pet shop took him in from a neglected tank and he didn’t have a tail when they got him.
My girl’s getting so big
