My CRS Colony


OzShrimp

Recommended Posts

My CRS colony appears to have dwindled upon close inspection however upon looking at @Disciple's tank photos i was inspired to take some of my own after seeing Elvis junior at the front of the tank. He is offspring to the shrimp in my signature and most expensive shrimp i ever brought lol.

i dont really cull though unless they absolutely suck, i am breeding for colour depth as opposed to grades

You've done well Shaun. I remember you're ups and downs with this tank. It's nice to see the shrimp swarm.

yeah well town water of tds 580 didnt help to begin with did it lol.

I have had more downs then ups but it was the generosity of some on here that got me back in teh game when all my shrimp died 2 1/2 years ago :)

 

its a shame its an 8 1/2 hr drive to your work now @Heavyd lol so no regular shrimp visits. I still got my tank from back then but sitting idly in the garage, once i move i will sell it

Haven’t seen you around for a while Oz! Do you still have any tanks going?

Hi Shaun how are you doing. I remember your shrimp. It was the same time Jamie and I had the large colonies too but I think perhaps the quality of yours may have topped mine. Do you have any tanks now 

I just looked through my thread but my pictures don’t show up anymore because I used photobucket and haven’t kept up my membership so all photos lost on there

Hope you stick around more often @OzShrimp.

I would be good to get the old members back on SKFA. 

Sort of like a virtual reunion. ?

      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)
