Help! Identifying PRL gender


sanmasterp

Recommended Posts

Hey guys, I'm having trouble identifying the gender of this PRL shrimp and would appreciate any advice on if it is male or female. Still new to the shrimp world as and I've been able to identify RCS rather easily but have a harder time with the PRL crystals for some reason. Sometimes this shrimp looks like a male and sometimes it looks like a female ..

Is it a juvenile?

If it is, then it could be a female.

Another trick to ID them is to check their antenna length.

Female = antenna is about the same length as it's body, a little longer perhaps.

Male = Antenna is 1.5 times it's body length.

I have no idea where to draw the line between juvie and adult but I believe its a adult about 3/4 inch. And when you say antenna length longer than its body do you mean the whole length of the shrimp from nose to tail ? It's antenna length is a little longer than its whole length from nose to tail if thats what you mean.

I think of Juvies as Teenagers. That is, not fully grown to it's full size.

Yes, antenna length from nose to tail. Best to check when the shrimp angles it's antenna towards it's tail. 

If the antenna length is only a little longer than it's body(head to tail) length, it's a male.

If the antenna length is much longer than it's body by 1.5 times, than it's a female.

Hey now... you can't have it both ways!!!

Ok... how does one tell if a probably male shrimp is sexually mature or a sneaky juvie female before her first set of eggs??

It's not a completely goofy question - I've got a shrimp that I'd love to be a mature male so I can have him mate with as many females as I can find, but I can't tell if he's mature or not or a he at all.  If not, I should put the girls back into the main tank to mate with my second choice males so they don't just sit around.  At the moment, the hopefully mature male and his proposed harem are in a breeding box because I'd like to be able to keep track of the progeny. 

He's supposed to be an Aura Blue x Taitibee.  I don't know for sure about the Aura Blue part, but he sure is pretty and has a mostly clear body with a blueish head and a light sprinkling of tiger markings.

Thanks for all the great advice guys. I just wanted to come by and give a update. You guys were correct and she is a female. Since my original post, she has actually had 3 batches of babies so far totaling 30-40 shrimps that survived and is currently berried. She's my best female breeder currently and has made me proud!

1. The blue bolt is definitely a female

2. As for the tiger its a little iffy but I think I'm leaning more towards the side of it being a male

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
