Neocardinia Heteropoda Genetics


Recommended Posts

Hi everyone, I would like to learn more about Neocardinia Heteropoda genetics and I`m sure there are many knowledgeable people here (Dean :D)!! I have drawn up two punnet squares and was wanting to know if they are correct.

The "R" represents the red gene while (Which I assume is dominate) "r" represents the yellow gene (Which I again assume is recessive?).


Genotype "RR" (Phenotype "red") crossed with "rr" (Phenotype yellow)


Genotype "Rr" (Phenotype "red" with yellow gene) crossed with "Rr" (Phenotype "red" with yellow gene).

Are they correct and has anyone got any ideas on how we could get some more strains with co-dominance ect or can you only get new stains with getting lucky and getting shrimp with a slight, say, orange colour and breeding from there??

This thread is just to work out some genetics of the cherry shrimp and for people to share their knowledge.

I am pretty sure the colour is not caused by a single pair of alleles but rather a large combination of genes that work together to express the colour. I believe the strains were bred from wild type shrimp that exhibited small amounts of red and then the redest individuals were bred.

Ahh okay, thanks Matt. Hmmm.. If anyone else has got any ideas or anyone want to simple add anything feel free!!

      Great shot of Big Mama!  I reckon, 1 week tops for hatching.

      Great photo and news. The eggs are fading yellow but there are eyes so all looking good and there are a lot of eggs! Probably about half way ready to hatch.

      Let's hope the big mama can lay safely those eggs

      Sorry, I'm not in that area. 🙃   I prefer Glass tanks. Acrylic scratches way too easily. Often while cleaning algae off the sides. And once it's built up enough scratches, viewing gets obstructed.    Often going with LARGE tanks, you start to fall into custom built stands. So don't be surprised if you cannot find anything suitable.

      The easiest way wouod be to go to an aquarium shop and get a tank with a cabinet made for that tank, as that should be able to support the weight, as water in any large quantity is very heavy. I suspect it would have to be a glass aquarium at that capacity, otherwise the plastic would have to be very thick. It is possible to use a non aquarium specific piece of furniture but as you say it is quite risky, though I did help a friend do that by strengthening a nice decorative piece of furniture they had that they wanted to put a 350L tank on. It has been doing the job for 10 years but also bear in mind water marks, and we had to varnish many coats to make sure water doesn't soak into the wood etc. Its not really worth it in reality, it cost a lot of money to buy all the wood/stuff to strengthen it so was probably no cheaper, and a lot of time doing it. It may be dearer to get a combo tank and stand but much much easier and safer, and only you can know what ones you llike the appearance of? I would start off going to local stores and seeing if they have any you like, and even if not it will give you ideas?
