Hi Damien,

sorry to hijack the title of your previous thread :cool:

Though, this title is perfect for those pictures: 

I have set a tank with the water and soil of the creek, and this time it seems to work. Water is KH: 0, TDS : 30.

The one at the bottom is pregnant. This did happen in the tank , and I also have shrimplets. :happy:

Sorry for quality of pictures, they are from a phone.

That being said, these critters leave me perplex: I caught them in the wild, but they really look like the Hue bee (aka Princess Bee)...

Very cool shrimp mate. And well done on the breeding. 

Do you have the option of putting them under a microscope? If so, look for supra-orbital spines (see the article on Paratya / glass shrimp in the library). Chances are that these are one of the Paratya species native to New Caledonia.

Thanks mate, I'm currently updating the article to include some recent info on hybridisation and taxonomy.

Great to see Matuva! 
Interesting to see if the shrimplets will grow in your tank.

Hope we will succeed in breeding them.
My shrimplets don't survive in mine...

Thinking about rebuilding my entire tank. You'll have a lot of plants for your others aquariums :)

Thanks Damien.

The first shrimplets continue growing ;) They are now 4/5 millimeters big, so I can identify them as the ones from the chocolate shrimps with a cream stripe on the back, the one on the left on 1st picture.

I have yet to see the black & white beauty eggs hatching. I'm very impatient about that.

At least they are still alive, and still berried

Damien, time to swap to water & soil from south?

Please Please Please More pictures.

They are amazing shrimp and I wish you the best of luck with them.

I am guessing that no matter the colouration/ patterns of the parents you will get varying colours and patterns in the offspring, the offspring may even be chameleon- like in not sticking to a set colour or pattern in the aquarium. I guess the only way to tell would be to set up LOTS of tanks with individual pairs, matching a set male with a set female and then seeing what offspring they throw. And from there selecting the most desirable offspring and pairing them up again as single pairs to see what they produce. I think it could go either of two ways, either the shrimplets will be carbon copies of their parents or more likely you will find even greater variations between the original pairs and future generations.

Yes, I understand with what you say Baccus. I caught a 10th of new ones today, including some black tiger looking like. That's a thing I was wondering about: are all the different colors I find are just offspring's, or are they trully different?

Here are some pics of the new critters. Sorry for the poor quality, I really need to buy a better camera, rather than the one from my phone.
They are "reddish" for the moment, they will be black & white in 2 more days, after they settled in their new home and calm down.

With the red and white/ clear bands they look almost like a cross between a rilli and a crystal.

Have you managed to catch any in the act of breeding (long shot I know with a planted tank) but it might be worth keeping an eye out to see if males of any particular colour/ pattern show any preference for females of similar colour/ pattern. That to me would be a clear indicator of the shrimp being the same species or at least close genetically. If however the males just mate with any available female my guess would be that they are all the same species and the varying colours/ patterns you are seeing is natural selection at work. Namely throw out a mix of colours into an environment and the surviving colour/ pattern gets to breed while the more conspicuous ones get predated on and effectively remove their colour/ pattern from the population with only the odd throw back individual cropping up time to time, taking the chance that conditions had changed and that colour/ pattern could now be viable.

I have added a chiller on this tank and set the temperature at 22-23°C. I have also moved the 5 CRS and 3 white bees I have left in that tank, as it's parameters are the best for them. They become very active, instead of hidding like in the cherries tank.

As for the local ones, I believe there are different species. I have to re-order a book about those shrimps to narrow things. My last book was borrowed by a buddy who left to Canada and "forgot" to give my book back ?

Aaaargh! Found 2 huge planarias in this tank today :angry:

I have dosed No Planaria, just hope it is safe for these local shrimps...

Well, it seems No Planaria has done what it is made for. I saw a lot of planarias suffocating since the 1st day of treatment.

I have made the 30% water change after 72h, sadly, I found one CRS dead this morning :dark_mood:

Do another small water change by doing a surface gravel vac.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Shrimp and meds containing gentian violet

      By jayc · Posted

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?
