Been keeping these very cool natives for a while now. finally got the first batch of surviving bubs. very happy to find some running around the tank. They are a very interesting shrimp to keep and observe.

mostly the same stuff as the rest of the shrimp peas snowflake wafers zucchini occasionally dried anchovy and they snack on the reject cherry in the tank they seem to especially love parataya when the girls were sub adults they demolished about 100 in a few days so they will basically eat almost anything and lots of it.

They also seek and destroy pond snails.  Very handy.  Well done with the babies Paul.

 I had a couple of these in a 30cm cube on my desk for a while but the tank was too small and they would play "I'm gunna rip your arms off" until one day they took a leap of faith to the floor and dried up on the window sill (their faith was unfounded).

poor guys surprisingly I have 6 adults in a 2ft and no ripped off arms ever which given most accounts is very surprising. they are an awesome native to keep and given their size a lot easier too see things like them berry etc most things seem to be food for them they are true omnivores and will take advantage of any snacks.

I wonder if it has something to do with the age/sex/social structure of the shrimp. When I go spotlighting, I see them in thick densities but it is always one dominant male in a square metre or two, surrounded by ever increasing numbers of smaller shrimp (subdominant males and females). For example, one dominant male, a couple of subdominant males, half dozen adult females, 20 or so juveniles or sub adults. Whenever a dominant male moves into another's territory, the dominant male sees him off with his arms with generally no harm done. I wonder whether the shrimp in aquaria fight it out because they are trying to be alpha dominant.

quite possibly the females seem fine together but more than one male results in fighting and if they cant get away to the death in the end. the females wont share territory they all have their own patch in the tank and move away if another enters even when feeding.

      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!
