I started with about 20 and over 3 years just left them to breed without culling or selling - not recommended culling is very important to keep the quality up.- I ended up with about 1000 I guess - I did end up giving quite a few away at one time - now I have scaled right back and will probably only keep 12 or so of the best and cull out any low grades that might show up. Keeping 1or 2 really good males helps to keep the grades up, cull all other males and keep the best females. image.jpgimage.jpgimage.jpgimage.jpg

my first lot i started with 5-7 then they died when we bombed for cochroaches lol.

If your buying juveniles i would say atleast buy 10 so you got a good chance of get a female or 2

What size tank do you house your CRS in?

I had them in an oversize 3 foot tank an Aqua 0ne 980 which holds 215 litres, it had a large canister and 4 double sponge filters. I now use this for my TB colony with an extra canister added to it.

thanks for that, i have mine in a 4foot atm but i am thinking of going down to a smaller tank, ive heard that water quality is harder to maintain though in a smaller tank.

Basically depends on your routine maintainance I think. I prefer 24 " tanks for my breeding tanks , they hold a good amount of water, give the shrimp room to move and the WP's remain fairly stable including temperature. Others use smaller sections in bigger tanks. I have used 30cm cubes with success but temperature swings can be a problem. Good filtration and stable conditions are the main criteria I think. Good water movement so you don't get still areas in corners, just make sure the shrimp have hiding places to get out of the the water movement to graze.

Started with 20, 5 weeks ago and waiting for berrys to appear, defiantly have a few males pestering the females after their molted, still waiting. Housed in an aqua one 900 tank (half round).

@ineke I have been seeing the white flakes in your pictures and others for some time and was wondering what it actually is. Please advise my guess is food of some kind, thanks.

Yes that is Shrimp Snow. It is a soya bean waste product and although not particularly nutritious in itself it is the micro bacteria that grows on it that the shrimp graze on. It is safe to leave in the tank rather than having to take out any leftovers like a lot of  other foods. It's great for holiday food too. It's available from Boss Aquaria and New breed Aquatics.

Thanks @ineke thought it might be I haven't tried it myself however I will be getting some in the next order from @newbreed later this week. Thanks for the info and its uses.

I've never tried CRS due to them being a little more fiddly than other species but I keep about 100 or so RCS, rilli and Caridina sp in a 30L planted tank and they thrive. I started this tank with about 20 RCS, 10 Rilli and 3 Caridina (I had more in a community tank but they didn't do well in there)

Hitting winter and I've got about 10 buried so they must be happy.

I've got an air stone powered sponge filter and a small hob filter on it but that's all. The plants do most of the work.

I change about 4L of water once a week. (Icecream container) then fish the babies out and put them back in the tank.

Just quoted myself, this is a quick update finally the shrimplets are hatching and the first lot are getting their stripes it's a case of where's Wally attaching ourselves to the front of the aquarium with a magnifying glass stuck to our eye. Wondering what the poor shrimp think of the large eye looking in! We were lucky enough to watch one of the females help her shrimplets to hatch and swim off.

My CRS clan started with 15 and would have been up to around 600 at most! At any given time!

This was a standard three foot tank, fairly well planted!! Took a good eighteen months to get to best breeding rates!

Sadly lack of maintenance combined wih over feeding crashed the tank. Colony back to start again with around 20-30 juvies to su adults and around 15 shrimplets.

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
