I have a group of (presumed) Palaemonetes shrimp collected in a coastal area in Florida (Doctor's inlet, Jacksonville.) I've just spent a couple of hours trying to figure out what species they are. Given that I have the original species descriptions in front of me ( http://decapoda.nhm.org/pdfs/2575...

In honor of the 'Borneo Orange/Sunkist Orange' shrimp getting a proper scientific name (C. thambipillai), I finally digested my breeding journals down into a slightly-more readable article. Here it is: http://bogott.net/unspecified/?page_id=1415 Quick summary: The larvae like brackish water, ideally...

I got these from another hobbyist. He called them 'rainbow shrimp' and mentioned that individuals tend to change color frequently, foiling any of his attempts to breed a consistent line. I see them lighter and darker (ranging from the pale yellow shown below to nearly black) depending on background ...

I'm not really worried about your bacteria -- I was thinking that you were keeping the zooes in a green-water culture, and that the green water algae is most likely only suited to living in a marine environment. If you have the zooes in more-or-less clear water, then it might not matter. What I do, ...

Now and then I've found a few stragglers which had clearly been living in salt water (and growing, albeit slowly) for several months. I haven't ever tried to leave a whole batch of young in saltwater, though, so I don't know what your mortality would be. My main concern with your plan is that as you...

If you've made it to day 34 then you're definitely doing something right. The transformation to postlarvae is quite obvious when it happens -- they will stop hovering and swimming tail-first and start acting like grown-up, benthic shrimp. They'll sit for a few minutes, then zoom forward (much faster...

There's nothing in the tank but Nerites at the moment. I'm pretty sure that this is a veliger, based on comparisons with these: http://images.google.com/images?hl=en&q=veliger&btnG=Search+Images&gbv=2 Also, here's a film of the little dude swimming: http://www.flisrand.com/misc_images/ve...

I kept cherry shrimp in a 12-gallon nanocube for a year or so with good results. With the cube I have there are a bunch of foam blocks in the first phase of filtration -- I just made sure that a block was positioned so that it blocked the entire filter intake and that kept shrimp from getting sucked...

A close look this morning turned up some wiggly white dots. Under a microscope (at ~100x) they look like this:

I just turned the agitator off and looked for dots. There's the normal swirl of dust (which is the Tetraselmis, visible as individual specs at ~10 mics) but nothing noticeably bigger than the algae except a bit of non-motile debris. However, with my face up close, it looks to me like not all of the ...

I'll tell you that I have done this experiment a few years ago and also thought that I had "baby nerites" after seeing veligers all over the place.

Ah! That's more than I've seen. Mustafa, can you tell me what to look for? Are the veligers big enough to see with the naked eye?

I've had my nerites in seawater for several months with no sign of baby snails. So I'd guess that there's some step I'm missing. I haven't found any more info online about this species, but I've come across a few tantalizing details about other nerites. I'm starting to think that since many nerites ...

Badflash --

Any news about your brackish-water experiments? I have some olive nerites in full seawater with phytoplankton, and they lay lots of eggs capsules... but I can't really tell if the capsules are even hatching.

OK, I'm here! What's the word?

Good idea, Anne -- I put the larvae in a specimen box and balanced everything on its side. I have no idea how to embed a video in this post, but here are a couple of clips. http://www.flisrand.com/misc_images/LateStageZoe.mov (that's the zoe) http://www.flisrand.com/misc_images/postlarva.mov (that's...
