Hi all,
I've seen pictures of cherries of varying redness. Some are so light-coloured and almost translucent whereas others can be very red. Is it genetic or environmental?
Thanks!
I believe that it is both genetic and environmental. Males tend to be lighter in colour. For environmental conditions there is stress, which affects their colour as well as time of day/night, for instance for my shrimp tank, if I turn my lights on in the middle of the night, the cherry shrimp are mostly transparent.
Tank temperature probably has an impact as well as the intensity of lighting.
Then there are some Cherry shrimp that are just a deep red, while others are a disappointing red.

Those with stripes of red and almost transparent are male.
Brilliant red color are female cherry. It has been mentioned that wild form of cherry shrimp can be reddish brown. I have also read that this can also be due to inbreeding.
I personally have no experience in reproducing cherries till they become brown so i can't comment on that.
I have tested that lower PH do bring out the redness in cherry shrimp. I got 2 tank and one is higher PH (no CO2 . use onyx sand dark grey) and the other is ADA black soil (with co2). The red in the same shrimp really much more intense than in higher PH.
I bred more cherry shrimps than I can ever imagine. The red ones are usually the female ones and intense colouration comes from a very aged tank where the environment has not changed at all for sometime. Pregnant ones also exhibit more redness.
So I gather from Spinex and Joe's posts that female Cherries will naturally be red given a conducive environment whereas males will always be paler?
If so, that's good news coz all Cherries will be same/similar and there's no need to bother about quality or grading.
super red cheeries means that they R dieing i suppose...
yesterday saw a cherry super red..
machiam whackypt avatar...
but not tat intense...
today it died... -.-"""
lol...
Not really. It is possible that something which resulted it the shrimp dying also resulted in its being intense red. But redness does not equal impending death.
Also, I have both males and females which are very red. Males do seem to have darker red at least in one of my tanks.

I do believe redness comes in the genes too. Inbreeding many times will cause the colour to go off too. Hence I always buy from different sources every few months to reduce inbreeding.
From my breeding experience, as long as you don't disturb them and leave them to their own devices, they will be comfortable in their home and grow bloody red.
They prefer a stable environment to be comfortable, so don't do anything unnecessary to the water as well.
Ka Jiao them and watch their coloration fade. Keep on doing that and they may even become transparent!

All the 10 cherries I introduced into my 4' tank died within the week.Don't know whether it's the water parameters or the tetras/rasboras harassing them. Sigh.

i agree...Originally Posted by joe
now adays cherries dun looks asas last time liao...
I don't think the tetras/rasboras are harassing them even some bro has mentioned tetra has attacked shrimps before. If they are well fed, should not go for shrimps.All the 10 cherries I introduced into my 4' tank died within the week.

It should be your water paremeters, I think as I do not see anything likely with what u have stated for your setup. How long have u setup this tank? I would recommend at least wait for 3 weeks before introducing the shrimps again. Shrimps are more sensitive to water parameter changes and also nitrogen cycle chemicals.

2 ft planted tank, 2 ft low maintenance planted tank & planted shallow tank left now
that's why seldom see any comparison on cherries other than crs, probably the degree of redness hard to judge. Also recommendatiopn maintain genetic diversity after a few generations of breeding by introducing new cherry shrimp from other sources. This helps reduce the occurance of inbred deformities or weak shrimp.So I gather from Spinex and Joe's posts that female Cherries will naturally be red given a conducive environment whereas males will always be paler?

been to certain LFS selling cherries, but hard to determine their quality as they were being packed, doesn't show their true physical quality. also agree is difficult to find quality breed from other hobbist.
or maybe we can start posting pics whom owned cherries of quality breed. hopefully willing to sell also, this way maybe can maintain the level of quality breed of cherries here!
nowadays, i tend not to go to LFS to buy those big pack of cherries. Firstly, there's tend to have a higher chance of casualties inside them, secondly they would be scared stiff to show their true redness, thus making it difficult to judge. Nowadays, tend to get shrimps from home breeders instead. IMO, higher chance of getting a better redness of cherries
