Hummm.... will do. At the moment it's very small, when I first saw it I thought it was a piece of a molted skin.
I will keep an eye on it, though. The product used to get rid of them okay to use with shrimp, ya think?
Now 100% sure it's completely shrimp safe, but it doesn't bother any of the other critters in a reef tank. Pretty benign stuff from what i understand. Aiptasia X, or Joe's Juice are a couple of the top ones. Fill a syringe with the stuff and then coat the critter you want to get rid of. I got some aiptasia with some live rock i bought of craigslist. They aren't overwhelming, but you do need to keep watch for them and get them before they multiply. I have a 14g biocube that they appear in every few weeks. Very hard to get them all at one time once they take hold. More of just a PITA than something to get too worried about. Just thought I'd mention it before you had a bunch. Let me know off you have any other questions.
I had marine aquaria once, years ago, and loved all the cool critters that found their way into the tank via live rock. Back then live rock was barely "cured", from the ocean to your tank. Not cured meant many unhatched eggs waiting for the right conditions to hatch and colonize.
I had amphipods (sand fleas) by the millions in those tanks!
So... anyway... I'll be keeping a close eye on all these fascinating brackish-water-hardy-normally-ocean-dwelling inverts and will let ya know what's new as they show up... or disappear, whatever the case may be!
Tonight, in this picture, a small piece of Shirakura Shrimp Ball Food (don't ask for any more details, the rest is in Japanese! LOL!) This is the first time I've tried this food with the Opae, but all my other shrimp love it, so I decided to give it a try.
