Native caridina species breeding project!

[Crabby 230]

Hey everyone,

I was recently (meaning today) given the opportunity to set up a breeding tank for some native inverts (or some harder to breed fish I guess, but I want to go for shrimp) in a fishroom I help out in. I've been trying to decide what native shrimp I want to try breeding, but then I remembered that it's not as simple as exotics. Can I get some input from the 'experts' (@Grubs, @NoGi, @Baccus, @fishmosy, @jayc of course, I know most of you aren't very active anymore, but I would appreciate your help if you see this message) on what native invert you guys think is easiest to breed (for a semi-noob who hasn't kept natives before). I can set it up as brackish I think, we have an archer fish tank there and are setting up a saltwater as well so should have access to those tools and materials.  

Cheers!

Hey mate, sorry I've not kept anything for some time. Been too busy farting around with crypto and forex 🤣

Back in the day, things may have changed, zebra were extremely difficult to breed. A couple of guys had limited success, maybe a generation or two only.

Typus was hit and miss, i think those with ponds had better luck.

Riffles would probably be the easiest from your list. Maybe one of the guys here that are more active could assist you.

Oh sorry that's not what I meant, I was saying those were the species I am least likely to get a hold of! Pretty much most other natives I can do, just not really those 3 I think.

So I can do stuff like glass shrimp, DAS, Red nose, blackmore river, chameleons...

Great project!

Our native shrimp are so underestimated.

 

Well lets list out your options...

1) Darwin red nose - it's mostly clear but that red nose ! Fairly large compared to the next two.

2) Chameleon shrimp- similar to Caridina serratirostris and can change colours. Colour range from black to brown, reddish-orange, to light blues and greens. Also comes with racing stripes sometimes. The blues and Greens might be stress related, so less commonly seen.

3) Blackmore river shrimps - these are mostly clear with some rusty coloured spots. 

4) Darwin Algae Shrimp - aka DAS, similarly sized to the red nose. But by far the hardest to breed as the newly hatched shrimplets are tiny and needs planktons found only in brackish waters. 

5) Zebra - lovely little shrimp with it's black and white stripes. But seem be be another difficult to keep shrimp. Also very small at 2cm. They might be hard to source. You can always catch them in the wild but it means braving going into waters that crocs also inhabit. Zebra, from all accounts need very low TDS water. pH doesn't seem to matter so much. But TDS of 20-30 is key. However, it's easier said than done keeping TDS that low. An increase in TDS from 20-25 is a massive 20% change!  You most likely need to set up an auto water change in this zebra tank that replaces it with rain water constantly.

6) Typus - this is a large shrimp. Rarely seen in the trade now. These are probably the hardiest, if you can find any.

7) Riffles - I know you said unlikely to keep these. Just listing them for completeness.

Pair them up with any of our native snails and you will have a great biotope. Don't forget lots of leaf litter using our native tree leaves that have dried naturally.

 

Out of the 7 I'd start with Red nose and Chameleons. They can go in the same tank and they take the same water parameters. I wouldn't mix Blackmores, DAS or Chameleons in the same tank however, as you WILL loose track of which is which. 

 

 

Far out!

How the bloody hell are you mate ?!

Thanks so much jayc! Do you know what water params red nose and chameleons would breed best in?

Also I've heard it's best to avoid gum leaves in tanks because of the chemicals they leech/produce - any others to steer clear of?

Just asking because the water at in the fish room comes from a single source (big water tank that dechlorinates and mineralises - it’s pretty much a necessity when working with a load of large native fish in big tanks) and I’m not sure if it’ll be too hard or anything. I do need to test the water when it comes out though. I’ll do that tomorrow I think.

Cheers

Chameleons are indestructible provided you keep the temperature up. for instance i left a couple hundred in a sealed Styrofoam box full of rotting plants, peat moss and bog wood for 10 days by accident when moving house and still managed to get at least 50 survivors out of water that smelled and looked like sewage.

I find Paratya are the easiest.    The variety you can buy online from livefish.com.au certainly reproduce easily.  I have Paratya sprinkled into ponds and various unheated and heated tanks for algae control so they cope with a wide variety of temps.  They do die off a bit in outdoor ponds in Melbourne in winter when water can be < 10C.

Chameleon shrimp will also certainly go ballistic under the right conditions but I also find they will stop breeding and the population will decline but persist with lower numbers.  I try to keep Chameleons in a couple of tanks at any one time to ensure I don't lose them.  Mine do OK on Mulberry leaves but I think they like a bit of protein.  The best numbers I had were in a tank with some catfish that died and the shrimp ate them and bred like crazy.

I’m probably being naive here, but can’t you just go down to Parramatta river, get some water in a tub, and put the larvae in there?

Then replace 10-20% of the water with new salt water so you could potentially introduce/ replace the micro fauna that have been eaten?

[Crabby 230]

Thanks Grubs, I had been thinking paratya could be pretty easy, so if I end up failing with one of the species (DRN or chameleons) I'll try out the glass shrimp. Also will make sure I feed protein. As we have a barramundi in the fishroom he eats frozen pilchards - I'm sure I could just chuck in a chunk for them once every couple of weeks. What params do you keep yours in? (Paratya and chameleons, and DRN if you keep them as well pls).

Robbie, which species were you thinking about for that method? While I can't get water from Parramata river (as I'm in Melbourne, Vic) I do have a few local rivers that I can collect water from pretty easily. Paratya live in most of these as well, so it should be pretty safe water.
