Hey everyone,

I read an offhand comment somewhere about yellow cherries dropping more male shrimplets than females and looking at my yellows I'm starting to worry they may all be male. I have around 25 that I got about a month ago from two different breeders, about 5 are around adult size and the rest are around 1cm. They are all very nicely coloured but the adults all look male in shape and none have saddles and the juveniles look male too.

I'm hoping that I just can't tell for the juvies yet as the male:female colour difference isn't as obvious as in the red cherries and they might be too young to have hit shrimpy puberty and got their curves yet. I can usually tell really young with the RCS.

Is it possible/likely I just won the all male shrimp lotto?

Anyone who breeds them know if there really is a weird sex ratio quirk to the yellow variety?

As you mentioned it is harder to tell the difference when they are young so you can't really be sure, when you're just starting out, of their sex until they start showing saddles, which is usually around 15-20mm. As you gain more experience you'll be able to tell a bit younger, but even now I have trouble telling with yellows cause their colour is a lot lighter than most other cherries. I would keep observing them until you are sure that they are old enough to start breeding, generally about 3 months old. :encouragement:

Yeah. I will do that then. Worst case scenario, I have an excuse to buy more shrimp in a few months time. :P

If you have the issue of a domination of one or the other sex, altering your water parameters with alter the sex ratios. as in Temperature and PH has total control of the sex ratios. I have not done the experiments to find out how it goes, But with everything else those two are the main factors in sex selection.

My ratios change with my water conditions, I will have to document it. Yes I don't test I just water change but I have really good water up here, I also have Crystals outside without chillers. for now.

Even the most experienced will get sexing shrimp wrong sometimes...

LOL I even drink it right from the tap.

Sorry it is such a nice change to have good water after growing up keeping fish in Brisvagas

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      That shrimp itself survived the molt just fine, but left about half dozen eggs still in the shell. I haven't measured KH in a really long time, but assume it is zero since I don't have any rocks besides a few small pieces of lava rock.  Maybe you have unwanted rocks in your tank?  My tank is the "long" style which I really like because I have a HMF on one end, and a pump outlet spout that shoots water all the way to the other end.  I have no idea how many shimp it can support because I don't really understand waste management in a tank.  Shrimp poop eventually turns into mulm, but then what?

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      Thats a great photo, beautiful blue bolt, I hope it survived the molt without dropping the eggs! I think I can just about see some black dots (eyes) on the central egg but can't be 100% sure. I used to (and plan to again) do weekly water change of 10-15% but if you do too large or quick (not drip in new water) that would likely trigger a molt. What KH are they in, my new setup is sitting at (and refusing to budge) KH 3 and PH 7.5 so I may have to settle for neocaridina shrimp this time as opposed to the caridina I want, though not looking/deciding just yet, give the tank a bit more of a run in! Tap water here starts at kH 14, tds 320, when filtered goes to KH 0 and PH 6 but when put in the tank keeps going to KH3 and PH 7.5 despite 3 x 50% water changes???? You may be at 'maximum capacity' with only 20L tank especially if the tank is a cube type rather than shallow type?

      Right now this tank only has blue bolts and golden bee (red bolts?).  The eggs start off all brown, but at the end, I notice that some are kind of a clear pink-ish color.  So I don't know if that is the egg color of dud or golden bee.  Picture of shrimp only about half hour before molting. The water is always RO + remineralizer, so it should be ok. The tank seems to still be on a "good streak" ever since I started the regimen of weekly water change, monthly gravel vac and plant trim.  The point being to keep the amount of waste low and removing moss / floating plants so that the nitrates go towards growing algae.  At one point, I had three berried females, but only netted about half dozen babies by the end, due to this early molting problem.  There might be about 30-40 shrimp total in 5 gallons, but still very few full-sized adults.
