Breeding Celestial Danios cohabitating with Cherry Shrimp

[xanderman]

Does anyone have a definitive answer as to whether the Red Cherry Shrimp will consume the eggs of the Celestial Pearl Danios, such as fecundity ratios between a control with no RCS and reproductive rates in a mixed tank?
Perhaps number of fry/time span in species tank compared to mixed?
Also, if anyone has information on fry survival rates over longer periods with cohabitation with RCS, due to predation on baby shrimp and increased food quality/availability for CPD?

I am looking for very specific qualitative information, objective data based conclusions, not specualtion.

Hi

I’ve not managed to find anything as yet. I’m guessing (apologies) that the cpds will have a munch on some of the young shrimp and the large shrimp will do the same to some eggs. Once I make space, I’m getting another group, and will not keep shrimp with them to see if it makes any difference.

Thanks Tom, I guess the species is so new to the market that little is known about it.
I’ll have to see if my wife will allow another tank… or wait for someone else to figure it out.
Maybe the food will offset predation, depending on a balance between the populations.
Like, 1000 RCS and 6 CPD will make it very unlikely that any eggs will survive, whereas 1000 CPD and a few shrimp will make the effect negligible.

I did see yesterday on fishprofiles.com that while the shrimp are primarily an algae eater they are opportunistic scavengers also, and it specifically mentioned that they will eat the eggs of scatterers like the Danios.

[Tom2006]

With my shrimp they jump on anything other than algae although I’m sure they do eat some algae. I’m guessing a nice ripe fish egg would be a nice treat. Who knows, will have to do some breeding and find out. lol

[xanderman]

I see that fishprofiles.com also says the Red Cherry Shrimp will also eat fry which are not free swimming…
I’m thinking I might have to reduce the population of shrimp to have a successful brood of Danios.
The males are definitely interested in making it happen, coloring up a bit too, just need to get the females fattened up a bit.

[Tom2006]

I think its the best way forward. I love my shrimp…not as much as the CPD’s though. Once I clear a tank in the garage I’m going to get some CPDs in there

[xanderman]

Well, these little guys have been in with the shrimp for a month and a half, with no babies showing up. Looks like they’re very happy, and there are some breeding behaviours, but no succesful spawns.
I’ve started thinning out the cherry shrimp, removing about fourty males, and we’ll see what happens in a month…

[Tom2006]

I have been having mixed results. So far got approx 7-8 youngsters growing up with my adults and the cherry shrimp. I think its down to the adults rather than the shrimp although I’m sure the shrimp will get a few eggs.

Hi,

I always use shrimp in my breeding tanks, always cherry’s, or a species related to the red sherry’s, Neocaridina heteropoda sp.
Only the species like Macrobrachium can do dammage to the egs and the fry, and even to the fisch.
Snails on the other hand can eat the egs, or at least dammage them.
I breed cpd sinds 2007 now in large numbers.

greetz Monica.

P.s.i’m new here, did not now that this forum existit.
My enlisch can be very bad, my apolegise , i don’t use a translate program :oops: .

Hi Monica….WELCOME!!

Your English is great!!!….do you have a run down on your set up (s)? Sounds like you are breeding quite a few? Any tips you can offer us?

Hi Tom, thank you for te welkom !

A run down on my set up, i don’t now…what is a run down?? (now you see how bad my englisch is :oops: )
I’m breeding a lot off these fish, somtimes i’ve got > 500(several spawns), somtimes les.
On my attick i have 12 tanks in different sises, not nice to look at, but functional.
I always take 5 well fed fish, 2 female’s and 3 males (the alfa’s), and i put them in a tank with java moos , and very much plants.
The waterlevel is only 25/30 cm, no filter, only a airstone (is that the right word?)
In the time they are in the breeding tank, i feed them with live food like brine shrimp, and red muscito larve (the black one’s stay to high by the waterlevel, and so do the white one’s to).
That on a dayly base.
These fish aet mostely from the bottom off the tank while spawning.
Feeding them while spawning prefent them from aeting most of the eggs and fry.
The fry that make it to the watersurvase wil therefore survive :wink:

After 5 til 7 days i take my 5 fish out the tank and than i wait.
My newest experiment is breeding in a bucket…that also works fine, and is a nice low budget solution :lol:

The biggest spawn i had was over 180 fry from 5 fish in 5 days….yes i’m addicted :roll: :lol:

Here a few pics, sorry for the bad quality, its a simple camera, and i’m not so good in making pictures :lol:

This is a 80 cm tank and in these tank are 240, 8 and 10 week old fry on the picture aeting brine shrimp.

An ugly photo, but these where the 180+ fry, from 1 single spawn.

[Tom2006]

Thats brilliant!! A run down is just what you have done. Given us a description/view of your tanks and how you breed them! You are very successful!!

Would you be able to start your own thread in this breeding section. I would love to know how you use a bucket to breed them please? I have some young fish but not many. I would love to get more to increase my shoal size.

Hi Monica, welcome to the forum.

I’ve been using small plastic containers to hold the moss and then switching the containers out every 3 to 5 days. I’ve had pretty good success, but nothing compared to the success you’ve been having.

Thanks for the set-up info, I’ll have to give it a try!

Does anyone have an issue with their young having problems swimming and then eventually dying?

I have had a few fry from various spawns make it past the adults but quite a number of them, at about 7mm onwards start to struggle to swim and sort of flick upwards as if they can’t hold themselves in the water. I’ve got two at nearly 2cm and one has started to do this stange swimming action ever so slightly. I’m feeding them red crumb food and baby brine shrimp. The adults are in the same tank and never display this behaviour so it must be something I’m doing wrong with the youngsters

[BallAquatics]

Hi Tom,

I think they all go through a stage of this at some point in the development of their swim bladder. I’ve seen dozens of mine do this very thing, but they get over it in a day or so. I’ve never seen one of the adults do it, that’s why I assume it’s something linked to the growth process of the fry. Not a scientific answer, but just a casual observation… :wink:
