Neocaridina orange eyes
Nowadays, dwarf shrimp of the genus Neocaridina are established in the aquarium scene. In contrast to representatives of the genus Caridina, Neocaridina are somewhat less complicated and can usually be kept on tap water without any problems (herre in Germany and most parts of europe). Thanks to the work of passionate breeders, there is now a wide range of colourful, strong lines with stable inheritance. We offer some of them in our Standard Neocaridina category.
Apart from that, we are happy to be the only and first online shop to offer a very special category with many young, still unknown breeding lines that we created: Neocaridina with orange eyes (OE)! Here you can learn more about their appearance, heredity and new breeds that we would like to introduce to you!
Appearance
The orange eyes make a great contrast on the colored body. Characteristically, in Neocaridina they have a dark spot in the middle of the eye, which may indicate residual pigments. We published a detailed report on these animals in the Caridina magazine (issue 2/2022; german language).
The name "orange eyes/OE" is often criticized as a proper name for the orange eyes, since this abbreviation has long been an established term for the bright orange eyes of the Caridina. For this reason, we would like to point out at this point that Neocaridina OE are not comparable to those of the tiger shrimp (see above).
But there are also Caridina that have the orange eyes with a black spot, similar to the Neocaridina. The orange eyes of the white Caridina babaulti "albino" were called "red eye". The well-known breeder Skyfish from Taiwan, on the other hand, also calls the orange eyes of Caridina dennerli “golden/orange eye” despite the black spot in the middle.
Heredity & Genetics
It is a Mendelian recessive inheritance. For example, if you cross an orange-eyed Black Rose with a Blue Sapphire, you will get offspring that have black eyes 100% of the time. At the genetic level, however, these offspring carry the characteristic of OE, which is why one speaks of carrier animals in the F1 generation. Only when these carrier animals are crossed with each other or with parent animals will animals with orange eyes be obtained again in the subsequent or F2 generation with a probability of 25% or 50%. Body color is inherited completely independently of this. Some OE lines have already been crossed in this way, you can see an overview here:
These lines have already been successfully bred, but are currently being stabilized:
Dark Green Jade OE
Dark Green Jade OE
Orange Sakura OE
Blue Jelly OE
These intersections are currently being planned:
White Pearl OE
Red Rili OE
