My DRNS


Santa

Recommended Posts

Here are some Macro shots of my DRNS, taken with an attachable lens from my iphone!

Although I see plenty of berried females I am ever yet to see a baby survive to adulthood. Anyone have any tips?

Hi Santa,

I can't find the old thread, but I think @Baccus gave it a very good try trying to breed these guys without success ( apologies Baccus if I am losing my mind here).

Dave from Aquagreen knows how to breed them and it involves special greenwater culture with specific plankton, and also very specific leaf litter mulm in the bottom of the tank- no brackish water required for these. If you are super-keen, I think he sells some of that green starter culture.

I could not handle my DRNS girls being berried all the time and then the larvae covering my tank glass in thousands and then just dying off, so I split the males from the females into separate tanks. 

Good luck!

Wow thats a bummer that you weren't able to raise them up, I don't think I have even seen them in their larval stage though?

I shall definitely hit up Dave from aquagreen for that culture if he has some, sounds like it may be useful for my daphnia culture too!

I think Dave from Aquagreen manages to breed these guys by having them in outdoor ponds, this allows the green water and other micro-organisms to be in the system.

For the majority of my native shrimp namely Chameleon, DRN and Blackmore River Shrimp I have found the most survival rate of offspring when the tank is heavily planted, plenty of mulm in the tank and adding Indian Almond leaves. I would suggest the best filtration for a tank of native shrimp would be the old faithful airdriven wool filled filters these are less likely to suck small shrimp in and if they do get into the filter they are likely to just live it up on the gunk in the filter rather than being mangled in the internal workings.

Because the shrimplets are literally so tiny (smaller than even a newborn cherry shrimp) I find when doing water changes its best to use a length of airhose as the siphon hose, almost any mesh or netting you could put over a siphon hose the shrimplets will still go through.

Also when doing what changes do as Dave suggests and pre-age the new water. I don't always leave the new water outside but I do generally get a few days of the water aging in a tub that has had chlorine and chloramine remover added, before adding it to the native shrimp tank.

My DRNS reproduce in their tank but not in big numbers.  I use a sponge filter only and there is a fair bit of microscopic life in the water when you shine a torch through it at night but its not green water as such.  I had a fair bit of moss in the tank and I suspect this helps in providing a complex substrate for the larvae to drift into and find food.  I've not seen any planktonic larvae like DAS have - just tiny little DRNS appear "by magic".

They are currently in a tank with crs and cherries set up more for the crs (lower temp) and it definitely isn't as full of microbial life as it could be as I do have some pygmy corries in there too. Which may explain a lack of baby drns too.

I have also received a reply from Dave and was given a lot of helpful info on a green water culture but from what I can gather they don't sell starter cultures.

      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!

      Hi SKF!   So I bought some PRL (or at least they were sold as such. These claims are dubious in Australia as people don't know much about the genetics, nor do they care as long as they can make a quick buck). After 8 generations of breeding true, I'm having around 1 in 200 throw a much darker red. They almost look like Red Shadows, but I don't know too much about those types of hybrid. Can anyone help with ID'ing the gene?   TIA (First 2 pics are the weird throws, second photo is their siblings and the last photo is the parents)
