Thats quite a nice collection of varying colours, did you buy them as a 'skittle' mix. I have always especially liked the yellow with the stripe along the back. A friends daughter popped round on saturday as she wants to get a 'skittle' mix for her tank. The supplier I use only sends females, I guess to avoid them cross breeding and producing brown 'wild' types but I expect she already has some of my 'wilds' so there will likely be some males already in her tank, so they will likeily breed? Even with the one colour (reds) that I have in one tank, they still produce brown 'wilds' which I just give away when I catch them, to a friend who dumps them in his big tank. I expect I will restock some more reds when I order the skittles mix for my friends daughter, after their holiday, so not just yet.
I bow to JayC greater experience and knowledge, but suspect the original shrimp this thread was about is a female as you can see the circular middle shell that females have to protect the eggs etc. It is difficult to tell from the photo, especially when the shrimp isn' stretched out fully straight! I still suspect it to be a 'red bolt' every time I look, the legs are patterned, I don't think I have ever seen that with a cherry shrimp? Hopefully it will do well but won't breed with cherry shrimp if it is a caridina.
Do you have snails as there looks likr clear jelly type spots on the glass that may be snail eggs?
