Breeding population of shrimp to sustain a semi-aggressive community?

So I am interested of getting Cherry Shrimps - hardy, and easy to breed they say. But of course I know they are instant live food for aggressive fish species.

I have a 65 gallon, fairly planted tank, with a school of 9 tiger barbs. Do you guys think it is possible to (1.)house a certain number of shrimps that can live long enough to: breed and maintain population despite the imminent deaths from the Barbs? If yes, how many? I'll try to add more plants and hiding places for the shrimps if necessary. This is part of my experiment of have a self-sustaining tank. If the answer is NO because the barbs will absolutely kill them all, then I am happy to move away fro this idea

Additional questions:
2. How long cherry shrimps live? (let's say they managed to avoid getting eaten)
3. How long does it take for them to breed after obtaining adults from the shop?
4. How long does it take for the babies/fry/whatever you call em, to grow old enough to breed themselves?

added note: I also have 5 mollies (4 females) that I am hoping will populate the tank with fry - bonus free food for the barbs from time to time.

im probably way off but I think they live for seven years I think?....
few weeks maybe days
months
Tiger barbs are mid tank, do you have a Heavily planted tank? that's the only way I'd see them live.

this is my tank at 2 weeks old. Will definitely add more plants soon. Kind of messy setup, but I am aiming to replicate the natural habitat of barbs - dirt-gravel-sand substrate, with rocks, twigs and dried leaves for more 'natural look'

Cherries live a little over a year. Your tank doesn't have that much plants, if you want to have a decent size colony you should have a large plant load like you can barely see the substrate large. Now here is the thing if one if your shrimps die and the barbs eat it they will realize how good it taste and will start hunting for live ones but if you have a large plant cover then most will hide and survive but will barely be seen......

Noted - will add more plants before getting shrimps. How many shrimps do I need to get initially to have a "decent size colony" that can successfully breed in my setup?

As others have said, you need a lot more plants / hiding places for them to survive.

I would highly recommend building a colony in a little 10 gallon tank or something and then transfer them all into the bigger tank once you have a hundred or so adults (should take a few months).

Usually you want a large, established colony in the tank before introducing fish, so that's my workaround

To answer your other questions:

How long it takes for adults from the LFS to breed depends - it could be immediate (or even already berried) or could be a month. Adults don't acclimate quite as well as younger shrimp.

As for birth to reproducing, I think it's around 6 weeks depending on temperature. The higher the temp (within their range), the faster they grow and the shorter the gestation period. The downside is shorter life and higher risk of bacterial infections.

1. house a certain number of shrimps that can live long enough to: breed and maintain population despite the imminent deaths from the Barbs? If yes, how many?
Possibly, but I saw ditto on setting up a separate tank and once you get some offspring in there that are rather large, you can then try introducing them into the community tank.


2. How long cherry shrimps live? (let's say they managed to avoid getting eaten)
Typically 1-2 years

Amanos can live for 10+ years potentially, but their offspring cannot survive in fresh water.


3. How long does it take for them to breed after obtaining adults from the shop?
As stated, varies.


4. How long does it take for the babies/fry/whatever you call em, to grow old enough to breed themselves?
Juvies (babies) may take 3-6 months before they start reproducing, if conditions are good.



A good question is... do you know the GH, KH and TDS of your water?

I would dedicate at least one corner to a giant moss bush.

It's much easier when you start with shrimps. Let them breed, establish a nice colony and then put fish in the tank, but it's too late for that ;-)
You would have to plant much more than that and add mosses, as much as you can. Then you could try adding shrimp, but I would try with a decent number, like 20-30 at least.

Yes I agree.. But I am afraid the idea came too late

Thanks for all the guidance everyone! I appreciate them... Now let me put more plants first. Once they are all growing thick, then let's see if I can push with the shrimp idea. Cheers!

IMO, it's good to know. A lot of people do great in keeping cherries in untreated tap water. I do that? They die. A local breeder who has *very* similar water as to what I have uses straight tap. Her shrimp do fine! Mine die due to a lack of minerals.... The main difference is that despite having basically the same water, her tanks are much older and "dirtier" (she doesn't top up with RO water, only tap) so it has higher GH, KH and TDS. Inside tanks run around 200-300 TDS and she has shrimp outside in a half whiskey barrel in TDS at 500-600+. What comes out of our tap is around 40-60 TDS...

What is the temperature of the water where they live?

have you considered glass or ghost shrimp, much cheaper then cherries nearly all fishstore carry them as cheap feeders for fish. I used them for years feeding large eels ... tiretrac, fire and such. Never got a colony even with 50 or more at a time, they got ate before that could happen.
