NQ Algae Shrimp 'type 2' ( Caridina spp )


Recommended Posts

Has anyone got any info on the main differences between North Queensland Algae shrimp - Caridina longirostris

NQ algae shrimp type 2 - Caridina spp 

Darwin algae shrimp - Caridina sp NTnilotica

Is their many other variations in Australian natives available in the trade? 

The only other native species in the hobby I am aware of are:

• Darwin Red Nose Shrimp - Caridina sp Gulf1
• North Australian Chameleon Shrimp -
Caridina sp WA 4
• Blackmore River Caridina - Caridina sp. NT2
• Australian Amano Shrimp - Caridina Typus
Riffle shrimp - Australatya Striolata
• CWC algae eaters - Caridinides wilkinsi
• Queensland Zebra Shrimp - Caridina cf. Babaulti

Hopefully I've correctly matched the scientific names. Please correct me if I'm wrong. I understand natives are still being discovered and re classified all the time but would love for someone more knowledgeable to discuss the ins and outs. TIA.

You've listed all the natives I know of.

Aquagreen has an article on some of them ... https://www.aquagreen.com.au/files/Freshwater_Shrimps_of_NT.pdf


NQ Algae Shrimp and Darwin Algae Shrimp are very similar, except for markings and colouration.

DAS has a white stripe from rostrum to tail. And they can be a light green or red or orange in colour.

Whereas the NQA is very transparent in colour.

Apart from that, they are very easily mistaken for each other.

Thanks mate. Cheers for the articles, good read.

Aqua green is awesome. I plan to buy some off him in the future. The postage is the only thing putting me off as I'm in Sydney.

I really wish there was more info on the 'type 2' though. That's how it is with Australian species though.

      So as some of you know I have a thing for Chameleon Shrimp, so when I decided to re-do my tank and add only Chameleon Shrimp with no other Shrimp and some Threadfin Rainbows, I thought they would all be fine seeing the Threadfin Rainbows have such a small mouth and throat.
      So today I decided to have a little scope around the tank to see if I could find any Chameleon and have to say I'm pretty disappointed, so far have only found 3 adults, out of a possible 40+.
      I'm gathering the Threads have taken to the Chams, sadly.
      So what now? Do I just leave the tank with what Chams are left in there amongst the Threads? Or, should I look to do a small Cham only tank? Really not too sure, wanted to just focus on 1 tank, but now... not too sure, I do really like the idea of a Cham only tank.
      Could it be unheated? Seeing it's indoors? Does it need to be filtered? Seeing it's a Cham only tank? Should I go for a small planted Betta tank? Or a small planted Nano tank? Or, could I perhaps do a planted plastic/glass vase or bowl? Ideas are there, the Chams aren't though, a bit disappointing really.

      Welcome to SKFA. It's a Macrobrachium of some sort. Those claws give it away. But don't know which exact species of Macrobrachium. Might be able to narrow it down to which species if we knew where the shipment was from. Where are you from?   Don't put this fella in a tank with other Neo Caridina or Caridina or Taiwan bee shrimps. It will eat those smaller shrimp.

      Hey all! First of all, thanks for the add!  I really appreciate it!  I hope I am not breaking any rules by posting this in this thread, so if I am, please relocate this post to where it belongs!!  So, about a week or so ago I got a blue crayfish from the local pet store, and they told me that this "Little Dude" (His name!) was sent along with that shipment in error and it wasn't identified, or at least the pet store didn't know what it was, or told me it was another type of crayfish.  After his first molt (Just last night and the fastest to complete one yet) he is a different color, slightly bigger, and I don't think he is a crayfish at all.  I am thinking he is a shrimp, but I am not sure.  If someone could confirm this for me, and possibly even identify what species of shrimp it is, that would be amazing!!  Please don't judge the dirty tank I have been working and then he molted so I haven't had a chance to clean it properly in a little bit.  I appreciate the help!

      Great news that everything seems to have settled down! When you do set up a new folter system, leave the old sponge in the tank for a couple of weeks while new one is running as it will be full of bacteria but the new one won't have any at the start etc!

      It's been awhile but things have been going ok. I got my water parameters back to around where it needs to be. KH back to 4 but I can't seem to increase GH past 5, even if I only add GH remineralizer back during a water change. Anyhow, the tank has been stable. I haven't seen many shrimp deaths or anything alarming. They are still consistently breeding. I do have to feed them much more aggressively, on a daily basis. I also started to add in mulberry and dandelion leaves for them to graze on every few days on top of the other foods. They are a bunch of hungry buggers. I need to swap to a more powerful filtration system than a sponge filter system. While the shrimp poop is awesome for growing my plants, the water has become dank and dark. I'm fine with tannins, but there are way too many particulates in the water. Going to swap to a mini canister filter system with a spin pipe to keep water flow low.. so things are going to get shook up a bit again, but hopefully it all stays stable.

      Simon, Thanks for your input. I will recheck my water parameters. Don
