Just been browsing online relative to Red Cherry Shrimp (red ones) looking to purchase a few more perhaps.
Yes, mine are breeding extremely well but I'm inclined to think including a new line of the same strain will improve things somewhat and having sold a few, am always interested in what people perceive as being appropriate pricing.
That being said, I would like to ask what everyone thought were fair prices for the following:
Cherry Adult Juveniles
Sakura Adult Juveniles
Fire Red Juveniles
Fire Red Adults
Painted Fire Red Juveniles
Painted Fire Red Adults
Just price red shrimp presently, we will look at the others in due course but imagine you were selling yours on Gumtree, Petlink, eBay or similar, what would be a fair price to the hobbyist after his efforts and costs and what what be a fair price to the buyer do you think?
I have included a couple of unobtrusive (I hope) Google Adsense ads in the header and footer, if it earns a few pennies this will go to the cost of hosting and any improvements about the place going forward.
If you see something flash before your eyes and thought "what was that", it may just be me moving/changing things as we go, my apologies for any disruption.
You might have also noticed some social media buttons under the posts and maybe worked out they are not working, kindly note we are working on their functionality and hope to have the issue resolved shortly.
Neocaridina davidi is a freshwater dwarf shrimp originally from Taiwan and is very common in aquariums.
Its natural coloration is in fact a greenish-brown, however a wide variety of colors including black, blue, orange, violet, red, green and red but its the red morph that is most frequently bought and sold.
The density and intensity of coloration on adult shrimp depending on their breeding will ultimately determine their final sale price and quality or grading.
Fully grown shrimp can achieve about 4 centimetres (1.6 in) in length and they prefer clean, stable water with a pH between 6.5 and 8, with a temperature between 14 and 29 °C (57-84 °F) but are probable most comfortable at 22 °C (72 °F) and all things being equal they will live for between one and two years.
These little fellows have previously been classified as Neocaridina heteropoda and Neocaridina denticulata sinensis, however are now known as Neocaridina davidi based on the oldest known published description of this particular species.
There is no question dwarf freshwater shrimp are both gorgeous and addictive.
So why can't I put different types of shrimp in together to make a vibrant color mix in my tank?
Because some types of shrimp require very specific water parameters which may not suit other types but beyond this, there is potential your different shrimp varieties could simply interbreed/crossbreed in the same tank.
This type of interbreeding between differing species or differing color morphs of a same species will produce hybrids that may not replicate the coloring of their parents, they may be something else entirely different.
Kewl To Create New Variety?
Generally the answer is no, given most of these new shrimp will resemble a wild version of their type.
Its likely they will be smaller and have lost much of their parents coloration with these animals usually more translucent and varying shades of pale brown and gray which are generally considered to be un-attractive.
One of the easiest ways to indentify if two shrimp varieties will interbreed is to determine their scientific names and make a comparison.
A scientific name is both the genus and species and so for the popular dwarf variety 'red cherry shrimp' (RCS) and using the scientific name of neocaridina davidi var. 'red' we can determine that its genus is neocaradina and its species is davidi with a red color variation.
A similarly popular dwarf freshwater variety are crystal red shrimp (CRS) having a scientific name of Caridina cf. cantonensis var. 'crystal red' where caridina is the genus and cantonensis is the species with a variation of 'crystal shrimp'.
Shrimp having identical genus and species will most certainly interbreed resulting in hybrids and ocassionally though NOT always shrimp having a similar genus name will interbreed, also resulting in a hybrid.
From the examples you see that red cherry shrimp (RCS) and crystal red shrimp (CRS) have differing genus meaning they will most certainly not interbreed but in the case of lets say, yellow shrimp (neocaridina davidi var. 'yellow') and the blue pearl shrimp (neocaridina cf. zhangjiajiensis var. 'blue') it is to be accepted that they will sucessfully interbreed given they share the same genus.
The good news to be taken from this is that is that shrimp with different genus will NOT interbreed and can be safely housed in the same tank.

Handsome Hybrids Hard
The reason creating hybrid shrimp is somewhat daunting is that shrimp don't breed like other organisms, whereby you can cross two different species and combine the best characteristics of both.
In the case of these little creatures, you cannot take a Yellow Shrimp and cross it with a Blue Shrimp to create a "Green Shrimp" ... sorry NOT gonna happen.
Usually, selective breeding is the way to create new colorful strains. With this type of selective breeding shrimps with colors of interest are taken from the wild, with the desired sought after colors breed out over future generations.
Having said that however, there are cases creating hybrids makes great sense and can result in absolutely gorgeous shrimp with a stable genus, checkout KingKong Panda shrimp if this holds your interest.

Interested to read some differing perspectives on Malaysian Trumpet Snails.
I just added a number to a 40L tank containing RCS believing them to be beneficial members of the community. I understand in certain circumstances they can present a problem, whats everyones thoughts on this?
