Priscilla Posted August 17, 2016 Report Share Posted August 17, 2016 Hi all, how do I tell my shrimps' gender? Thank you! Quote Link to comment Share on other sites More sharing options...
Aennedry Posted August 17, 2016 Report Share Posted August 17, 2016 It takes some practice. The underside of the males tail is on the straight side, females have a curve to protect eggs. Also on the female you can see what is called a saddle midway down her back. This is the ovaries. On the Opae Ula they are a very dark red. And of course females will be seen carrying eggs under her tail. =^._.^= Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...
Priscilla Posted August 19, 2016 Author Report Share Posted August 19, 2016 It will be hard to see them now right? Will we be able to tell their gender from the color of their insides? Like I have some that are black/dark brown and some that are white. Do they mean anything? Quote Link to comment Share on other sites More sharing options...
Aennedry Posted August 20, 2016 Report Share Posted August 20, 2016 The Opae'Ula vary in color, I have some nice dark ones down to some nearly white. If they have the dark brown area on the back that should be the saddle. Opae'Ula have very dark red eggs, so the immature eggs in the ovaries are dark. So I go under the assumption that any that have a saddle is a female and those who don't are male. Or immature females, I hear it takes seven months for them to mature. I haven't been able to tell very well on tail shape, because they are so small. How Many do you have? =^._.^= Quote Link to comment Share on other sites More sharing options...
Priscilla Posted August 20, 2016 Author Report Share Posted August 20, 2016 So we can't say that the black insides are females and white insides are males? I have 6 now! And I'm not sure their gender because I'm hoping for them to breed! Can you tell their genders from the pictures? Quote Link to comment Share on other sites More sharing options...
Aennedry Posted August 22, 2016 Report Share Posted August 22, 2016 The middle looks like a saddle. I had recieved Opae'Ula from two different sources, one arrived in March, the other September. The last batch had berried females two months later, the first didn't have berried females until eight months later, but half of them were berried. And I like your camera, I cannot get a good picture of my shrimp at all. How big is your tank/jar? =^._.^= Quote Link to comment Share on other sites More sharing options...
Priscilla Posted August 22, 2016 Author Report Share Posted August 22, 2016 Oh! So there might be a chance for me to see berried females then? Wow, 8 months is long I'm used an iPhone 6 to capture these images! My jar is only about 800ml but I'm thinking of upgrading to a slightly bigger jar. Can any other shrimps be kept w opae ula?

Aennedry Posted August 23, 2016 Report Share Posted August 23, 2016 Not that I know of. Opae'Ula are brackish water shrimp, the only ones I know of. All the other shrimp I keep are fresh water. There are salt water shrimp as well, but they will not go well with your shrimp. =^._.^= Quote Link to comment Share on other sites More sharing options...
Priscilla Posted August 23, 2016 Author Report Share Posted August 23, 2016 oh okay! Maybe I'll start a fresh water tank/jar once I see that my current one is stable! And do you know whats happening to my coral sand? Its turning yellow or like there's this yellow coating on them and on the glass as well.
