After some review, I think I identified this incorrectly It is Faxonius leptogonopodus

Picture of a non-color morphed one in the same tank(so same parameters)

So, I was recently collecting some crayfish during a fishing trip and came across an orange morph of this dwarf crayfish. The mena crayfish has a unique "leopard pattern" on the back. Which looks great in the orange color. It isn't the smallest dwarf, but it isn't huge. https://www.fs.usda.gov/detail/ouachita/home/?cid=fsm9_039755 I will try to get a better picture, but it is currently hanging out in my neocaridina tank. Hiding under a log and any attempt to get it out causes a lot of debris to kick up. I tried to collect some others for future breeding purposes, but ma

To be honest, I don't know which system decapoda use for sex. However, I posted that link because I wanted to quickly explain that while "binary sex chromosomes" are common, XX and XY are not. Also, some organisms(such as fish) don't use a binary system. Fish have 3 sex chromosomes! The other thing to note on neos is that males typically present less coloration, particularly when they are younger.

I've seen raccoon tiger shrimp pop up a few times. People generally note that they won't interbreed https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7142168/#!po=14.7059 Is this the same species? Sent from my PH-1 using Tapatalk

So, polygenic traits are more common. Neocaridinia are almost definitely polygenic CBS/CRS color doesnt seem to be polygenic. When you mix black/red shrimp, some will be black and some will be red. It seems to follow a single gene. I'm a little confused on tiger shrimp vs bee shrimp. Bee and tiger shrimp are the same species. Tiger shrimp are traditionally black, but they seem to use a different gene for black coloration. Because if you breed a black tiger with a red bee shrimp, you get crazy patterns. None of the offspring are red tigers. Sent from my PH-1 using Tapatalk

The last time this was discussed, this is how I basically understood it: Almost all of the domestic Bee/Tiger/Tangerine Tiger shrimp are hybrids at this point. Calling a domestic Bee Shrimp a C. cantonensis is a bit like calling a chicken a "junglefowl". Some genetic analysis was performed and basically, all of the Bee/Tiger/Tangerine Tiger are primarily C. cantonensis. This doesn't mean that they are entirely C. cantonensis, they are hybrids. It is just that the "base genetic stock" for all of the domestic strains of Bee/Tiger/Etc is C cantonensis. Wild-type C.

1) She would have all kinds of different "grades". Why? Because she would be rapidly pushing her shrimp population back to "wild-type". 2) The idea that they bred "true" isn't totally surprising. The colors you mentioned are NOT going to immediately breed out in 1 generation. Neos are different colors because they have a few pigmentation dots of different colors which can express in different intensities to create the entire rainbow(think of how your TV creates all of the colors from 3 colors). If memory serves, the 3 colors on neo shrimp are red, yellow, blue(primary colors).

I am somewhat interested as well in the C. Texanus. However, knowing how frequently they breed domestic crayfish together, I am not sure about the "C. Texanus". As I have discovered with the genetics on shrimp, things get tricky. The C. Texanus has a relative(C. Ninae, also about the same size) that is found very close to the home range of C. Texanus, but has generally lighter coloration. I have also seen several people refer to them as "Mexican" still, which may imply that they crossed them with CPOs. I am curious if anyone knows anything about the blue variety of C. Texanus. I ha

How do you catch? Trap or net?

@Psyklon Good luck. I used to live near where Cambarellus ninae lived(Rockport, TX). Cambarellus texanus was endemic too. I had a really difficult time finding any specimens. They typically live in areas with other crayfish and dwarf species are very good at hiding and are very shy. However, mollies and other live-bearers are RIDICULOUSLY easy to find. I was surprised how many different neat fish I could keep in my tank that I could catch locally.

Crayfish? As North Americans we live in the crayfish capital of the world. Do you plan to capture wild or purchase from the store?

Alright, throwing this one out to the wisdom of the crowd. Someone sent me down a rabbit hole recently when they pointed out that some research indicated that the Tangerine Tiger was actually not a C. serrata but rather a C. cantonensis. Despite the "red Tupfel" shrimp being a C. serrata, the Tangerine Tigers from the store all appear to be C. cantonensis http://easyshrimp.blogspot.com/p/caridina-cantonensis.html First, in 2005, there was a lot of destruction of Caridina serrata(I do have access to this paper). C. cantonensis was emphasized. Then in 2014, there was a new pro

Seeing if anyone is selling these crayfish. They seemed quite popular for awhile, then disappeared. From everything I heard, they were prolific breeders and survived quite well in shrimp tanks.
