Hi all

my cbs female recently dropped her babies and ive noticed the babies look red and white

Is this normal? Do they turn black after awhile?

cbs are all kept together with no other shrimp too

Thanks

Post a pic of the shrimplets and even the parents. Sounds like your CBS carries the CRS genes. CRS/CBS are very distinct even at the shrimplet stage and won't colour change. If you're selectively breeding, take the parents and shrimplets out, and only return whichever parent that you can be sure only carries the CBS genes.

In any selective breeding program, it is critical when introducing new stock to be 100% sure they won't contaminate your colony, as it can set the prigram back.

Hope this helps....

Thanks BB

Thats mum and a pic of the shrimplet that i can actually photograph.

Cbs were bought as a pack from skf and have been kept all together with no other shrimp.

Have found about 3 babies all of which are this colour

I have to agree with BB, I had a look at my shrimplets again this morning & there is a definite difference & I've never seen any change colour. You really have to be strict if you are selectively breeding & remove all the shrimplets & both parents as you don't know which one is carrying the CRS gene, it's a real bummer & could definitely set your program back a long way leaving them in. :cower:

Damn thats a real shame as i thought it was quality stock i was buying...

I purposely didnt mix them with anything and kept them together for that very reason

oh well looks like theres alot of work ahead...

I agree dude, that mamma is very nice! If you want to isolate the carrier of the CRS gene then I suggest putting the male & female in separate tanks & breed them with another CBS you know is 100% CBS & see what comes out of the offspring. It's a good month or two's work but it will be worth it if you can say for sure that that gorgeous SSS mamma is 100% CBS & therefore can be put back into your program population. :encouragement:

The CBS doesn't seem to have a solid black colouration, so I'd suspect it does have CRS/SW genetics through it. I've had my breeding colony breeding pure for 3-4 generation, and I've seen 1 SW pop out of the blue.LOL so it's a process, and if it's a simple process. shrimp keeping will be boring :-) Also, fertilisation only take a split second, so via transport, in holding tanks etc,.lol they can get contaminated.

More serious breeders overseas, would test/proof the genetics of the shrimp by isolating them and confirming their shrimps before adding it to their colony, in fear of contamination......

      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.

      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?
