After a couple of weeks in Europe, its good to be back in Aus and active here again.

Went out today and caught myself some riffle shrimp. Kept these before but haven't had any for nearly two years now. I caught six and they've gone in with my salmon red rainbowfish. Here is a few pics of one of the larger ones (probably female).

I've never bred them as I think i had only females. I've read they have live young and are easy to breed if set up in their own tank. I might try it one day, but i gotta catch some males first.

[h=2]Breeding[/h]Riffle shrimp is very interesting. They all born male and when they grow up to 3.5-5cm they change their sex and become female.

They are some very nice looking riffles indeed. I guess you just gotta catch some smaller riffles and you will have the males you're after.

I love the fact riffle shrimp are filter feeders. Not only do they look cool but they help to keep the water clean also.

True, thats why I think I've only ever had females. Seems like the spot i go to only has females. Seems to be a common theme as some other articles I've read mention only finding one sex in each location. I could easily find males but up till now the shrimp have been in with fish that would eat the males.

Watching them use their filter feeding legs is awesome. But don't think they only use their legs for filter feeding, they will use them to hold and pick up food much like other shrimp. Hence thats why you dont specifically need to feed them small particles, but it is cool to watch. Crushed up flake food, microworms, baby brine shrimp ect. will illicit the filtering response. I've also noticed they will learn feeding time and take up prime positions to grab the passing food.

They do get big, definitely good for our senior members, don't need your spectacles to see them.

I'll shoot you a PM Dean.

They are amazing, so big & so dark! Do you think they get lighter in your tank? :encouragement:

They can. Check out Deans video of his riffles, they are lighter. I think colour has to do with mood.

Yeah I've seen the video of Deans & I've seen them in other peoples tanks & they are a lot lighter, thought it might be a wild thing like with some fish when they loose colour when you put them in a tank :encouragement:

Possibly, Bob thinks blue colouration is a stress response, but I think it may also have to do with what they feed on, their environment (e.g. substrate colour, light) or mood as the ones I've seen are often dark, even before you net them (ie stress them). We both could be correct because there is some evidence that the northern populations (QLD) are a different species to southern populations (NSW and VIC) so could show colour in slightly different ways.

They are a great looking shrimp, may have to consider them again, but ONLY with a secure tank. They do tend to find a way out of the tank given the opportunity.

This is true but I think no more than other kinds of shrimp. I've seen and heard of plenty of escapee cherries!

Where would I find these in Melbourne/Vic, considering they'd live in somewhat cold streams/creeks here, would they adapt to a 22-23*C Tank, or would I be safer getting some from further north?

On the East coast near the NSW border, but I believe they are protected in VIC don't quote me on that.

I know one shop in VIC that has some northern ones

      Finally set up the 30L Shrimp Tank

      By sdlTBfanUK · Posted

      It has been a few weeks now and I have done a couple of large water changes. I tested the water parameters this morning, GH6 and KH2, TDS 140 and PH 7.5. Obviously the PH is off but there isn't anything in the tank that should cause the PH to rise to this figure so I will just run the tank for another month with 10% weekly water changes (probably just with RO water) and see where we are at that point. The RO water tests at PH6, and the KH and GH in the tank could come down as they are at the upper limits for Caridina shrimps! There are only about 10 very small snails in there at this point, but they seem to be doing well enough.

      Pure Red Line (PRL) Shrimps Western Australia seller

      By sdlTBfanUK · Posted

      I believe these to be very rare in Australia so you may even consider making it a longer term plan and produce your own by starting with the best CRS you can get as that is where the pure lines started! Depends how patient and interested in the project you are, but would save money as well? If I recall correctly it takes from 8 generations of selective breeding? They sell them at micro aquatic shop but do not ship to Western Australia, but that means they are available in Australia. https://microaquaticshop.com.au/products/pure-red-line-grade-ss-shrimp Good luck and just maybe smeone on here may point you in the right direction or be able to supply you with some.

      Is this garden hose end alloy pipe safe to use for aquarium piping?

      By Subtlefly · Posted

      Yes it’s super accurate to position where I want now and stay there- I am satisfied.  All the fish and shrimpers are doing excellent! Coming up on 4 years running!

      You must be pleased with that, it looks better and is much more robust and less likely to damage or leaks! The tank looks very natural now it has been running for a time. I see the ember tetras, how are the blue shrimp doing, I see a few? The cat and dog look very content and unimpressed, lol.
