Blue Cherry Shrimp - But Wait !

Recommended Posts

BlueBolts

There's been several discussions/queries on Blue Cherries, and I decided to do a simple experiment to demonstrate the growth colouration of "blue cherries" off choc parents.... I have removed 12 x "blue" juvi's out of my choc tank, and moved them to a isolation tank with different WP to determine whether this will effect their colouration etc.. after 24 hours, 1 of the blue cherries is turning dark/brown. The pics below are the colour spectrum of the blue cherries in this experiment.....from a royal blue to a aqua blue....

Will update this thread over the next few weeks, and/or once there are any changes...etc.

From past experience, the majority of the "blue" juvi's will turn brown, or a brown/blue hue....although my experience with cherries is limited.

Please comment, and/or share your thoughts/experience...

Cant wait to find out the results bb. I recently purchased a blue cherry and hoping that it stays blue. He is about 6-7 mm at the moment and is still blue. The seller did tell me he will refund the money if it does turn to other colour and that it shouldnt.

The shrimp is currently in the tank with the same wp as crs/cbs. Will check again when i get home from work.

Yeah, the blue cherry is tricky, and would be great if we got true blue F2/3 genes... no doubt we'll get there. I posted this pic a while ago, but he still remains blue to this day.... others are blue/brown, and my blue/brown & blue cherry realised a batch of shrimplets 2-3 weeks ago, and their blue is different, so fingers cross...

That looks almost purple bb haha. How have you crossed to get that color?

That shrimp looks insane! Hopefully you get true royal/deep blues out of the new batch. Good luck bb. Keep us updated.

great thread..

btw why is it that the blue gene is so hard to settle..?

probably because the blue genes have all been taken from other colour cherries! so i guess it will take a few more generations. patience my young padawan :)

7 of my 12 "BLUE" shrimplets have turned to various shades of brown....3 of them have a light/mid blue, which I suspect is from my Blue Velvet colony.... one of them is showing really nice potential, but will wait for another 3+ weeks to know for sure......

But what I want to know now, Marcus. Will they revert back to blue? Their colour is dependent on the environment you offer them. I've seen Cherrys go clear in bare tanks. Give them a few weeks and they get more colour.

Never...once they turn brown/black they'll never turn blue....

Interesting....

Would the resulting progeny bred from these shrimp be brown or blue?

Not too sure, but potentially the odds would be better .... I'm no genetic/cherry expert....

I find it odd that the wouldn't revert back to blue. If they have the genotype and phenotype for being blue. Environmental factors would cause a colour change, but by all rights, they'd have to revert back.

I'll wait to be schooled by everyone :)

I find it odd that the wouldn't revert back to blue. If they have the genotype and phenotype for being blue.

My fledgling understanding is that as shrimp mature and their chitinous shells develop and thicken towards moults, the pigments responsible for their colour also change (Not sure why, metabolic, respiratory pigments seen through a clearer shell of a youngster i.e. crabs have blue blood pigments vs final "camouflage" pigment selectively bred or not in the chitinous shell of an adult perhaps).

Yes they have a range of shades they can adopt; washed out or darkest dark when breeding pheromones flood the aquarium, but you can generally asume that their colour will be somewhere in between that. Blue in chocolate cherries seems to be one of those initial pigments that are lost once they come into adulthood.

Phenotype is all we can really go off in breeding and you choose your most suited specimen at breeding age not from happy memories of when it was tiny and kinda blue haha.

Its a damn shame that some with potential loose it as adults, I wish we could just use DNA sequencing to splice together some purple pigmentation!

      I am. I’ve looked at a few vendors. I ha w a buddy ordering from Aqua Huna in a few weeks, but I honestly don’t know if them import or tank breed. I know Flip tank breeds, he’s from my home state. I don’t know, but I have time to decide. I’m in no hurry.  Does the vendor you’re talking about sell only reds, or does he have other colors?

      I will consider it. I have an agreement with my wife that $100 a month each is our hobby allowance, and am behind on that by the tune of 6 months already at the moment. Patreon's and forum subscriptions count towards that so it may be a bit unless I sell some stuff (which is likely). I've owned a message board and been a moderator on several and understand server costs and the work that goes into these endeavors and particularly the difficulty of breaking even now that so many folks just use Reddit, FB, Instagram and so forth. It's a tough balance to give member perks to paid subscribers and not leave the nonpaying majority feeling like they can't enjoy the full forum. I admin'ed a corn snake forum where the owner decided to not allow nonpaying people have the ability to edit posts, and it resulted in a ton of members not sticking around -and the downfall of it being a popular place to post. I think to this day the most popular thread on that site is titled, "Show us you pets," and the site owner would not let me fix the typo. (insert roll eyes emoji) All of this to say that I understand restricting some privileges for non-paying folks, as well as the potential for free members not sticking around that it can have. For the time being, I will mark forums messages as spam to keep my phone from alerting me all day and hopefully kick a few bucks a month your way later on. I love international forums regarding our hobbies and the different approaches that seem to be regional and think these can enrich us all! Cheers, and thanks for the explanation.

      I believe those settings are only enabled for paid subscribers.  Consider supporting the forum,  your knowledge and experience will be most welcome here.    Just checking that you are clicking the "Notification Settings" as per the image below right?

      I was wanting to change my settings so that I do not get an email alert every time there's a reply or reaction to a post. Is this something that is disabled for new members?

      You're in the US, no? There's a guy on another forum who breeds nice CRS and sells them for $1 each +actual shipping. Home bred, hardy and beautiful shrimp with lots of positive feedback. Not sure of rules regarding crossposting, so will hold off for now, but if rules allow I'll post a link. Or PM me when you are ready. He's had this colony for years, so no need to rush. I only mention this because most vendors sell imports for between $5-10 each.
