Darwin Algae Eating Shrimp?

Recommended Posts

Crabby

Hey guys, just found an add for this website showcasing a cool-lookin native algae eating shrimp.
https://algaeeatingshrimp.com.au/products/australian-algae-eating-shrimp

Anyone heard of these before or own any? My interest was peaked by the claim that they eat hair-type algae, as I have some on my crypts and lace fern that I cannot remove. And for a price of $4 ea, and super easy parameters, they sound pretty doable! 
Tell me more oh great SKFians! 😁

(or feel free to point me towards an already existing page)

post-note: have you/do you keep these grubs? Seems like your sort of thing.

The photo is not a DAS.  The only place I know that breeds DAS commercially is Aquagreen  for half that price.  https://www.aquagreen.com.au/catalog.html

I do keep them and have bred them in the past but I don't have any excess at the moment.  I'm going to try and breed them again this summer.  They have marine larvae so are not easy but on the flip-side they live for 5 years or more and are hardy.

The photo at that site looks to be a Paratya  which will also eat filamentous algae but not as voraciously as DAS.  My Paratya came in the mail from https://www.livefish.com.au/tropicals/shrimp-and-crays.html

You can get them in local rivers but I find the ones from livefish do better in warmer tanks (Livefish are in QLD) - these breed in fresh water in your tank (easily).

Oh cool I've seen paratya locally as well, just a baby one tho, barely noticed him. Do they stay totally clear or have some different colours? 

And in terms of the DAS (as I think they are super cool), will they still thrive in freshwater? And how large do they grow? (I have a big grumpy apisto who might have a meal of any small shrimp - tho I'm getting rid of him soon possibly)

And for both of them, if I wanted to put them in with my TTS would they interbreed?

Thanks Grubs!

What Grubs said.

DAS is a little bit more colourful as well. You can get them at Aquagreen but just remember, they need brackish water and the plankton in it to breed. Or more accurately the newly hatched young need brackish water.

Yeah not planning on doing a breeding project just yet. Maybe late 2020, but not any time soon. If I were to get them I would just need to know that they will not fertilise my female tts.

tts as in Tangerine Tiger?

Hmm, no guarantees. they are both Caridina afterall.

Yeah tangerine tiger shrimp. I don’t think I would even mind that much if they procreated cuz I NEED MORE SHRIIIIIIMP!!!! 

(And the offspring would be cute)

Do they require much skill to take care of? (Either)

No nothing special. Just get them the right water parameters and that's it.

@Grubs might have the perfect water parameter requirements for DAS, so see if he can list them.

Otherwise, I used to keep DAS in water that was ph6.8 - 7.0, KH 4, GH6 and TDS of 200-230 and 25DegC. 

These shrimp from QLD seem to handle slightly higher temps.

Idk my tds but the rest sounds similar to my tap. If Grubs uses just dechlorinated tap water too then we probably would have the same parameters as we’re both in melb. And that’s my normal temp as well. 
How do you keep them @Grubs?

DAS are very robust and I've kept them in a tank with Melbourne tap water and in rainwater with  DIY hardness booster.  You'll find them in Northern Australia in both the fresh and brackish sections of rivers so they have really wide tolerances.  My tanks range from 24C to 29C

If you get some keep the covers on for the first 2 weeks as they can be jumpy if your water parameters are a long way from what they were housed in. After a couple of weeks they settle down and rarely jump.  I know some people with open tanks put gladwrap over the top for the first couple of weeks only.

I'll also suggest that no-way will they interbreed with your Tangerine Tigers -  they are very different shrimp and their bits wont fit together even if they were so inclined.

 

If money is tight then Paratya are about half the biomass but will breed up easily and also wont cross with the TT .... or do both.  You can keep all three together in the same tank.

Definitely tempting me here. 😁 

What do you feed them? As I currently feed my fish, and hope the shrimp get the leftovers. I’m looking more towards trying to feed my shrimp specifically though. I’ve tried zucchini and spinach, but only the hated snails will eat those. And rarely do I see a shrimp on an algae wafer. They all seem to be doing fine though, so I guess there's enough algae and biofilm for them to eat.

And if I were to get more shrimp with the possible intent of breeding them (not the das of course), would you recommend the removal of my Apistogramma pair? They’re beautiful and I would love to see them breed at some stage, but the are active and the male in particular is quite large. They can get a bit aggressive at times.

Hell Yeah! Apistos will snack on shrimps like there is no tomorrow.

 

There are so many things you can feed your shrimps. Go have a read of a few posts in the "food & nutrition" subforum.

Dang I thought u might say that... for some reason the guy at my rlfs (relatively local fish store) recommended them instead of honey gouramis as a bit of a feature fish. Are there any other ‘feature fish’ style fish that wouldn’t munch on my shrimp, or should I just stick with my endler trio?

I’ll check out the food stuff, thx.

      Hey guys, I thought I’d just make a single topic for my community tank, so I stop running around in other chats asking the same questions 😁. I’m going thru a big change in the tank at the moment, so will likely update in the morning with photos once the cloudiness is gone. Be prepared for a possibly very long message about a 10 hour process 😂.
      Cheerio!

      Hey guys, I’m going away for a few weeks and having a neighbour take care of my tank, as they are already gonna be caring for my cat during that period. I’ll be away for 2 and a half weeks, so not a huge amount of time, but the neighbour doesn’t have any experience with fish or shrimp tank maintenance.
      The tank will be fine without a water change during that time as long as I do one before I leave, I know that, but my 2 main problems are feeding and stopping my intake sponge from clogging up.
      For feeding I was considering getting a couple of pill boxes, like the ones that have seperate compartments for each day of the week, so I can set a certain amount for each day, and which foods.
      But for the intake sponge, I’m pretty stumped. My current intake is a sponge filter connected to the intake pipe, but it’s been clogging up once or twice a week due to how fine it is (and how messy my fish are). When it’s clogged, it puts strain on the canister filter’s motor, and that’s not good. I don’t trust her with cleaning it safely, plus I’m only paying her for 5 mins in the morning, and 5 at night. I’ve considered a mesh intake, but it looks like it could hurt a fish if it went past it quickly... plus I can’t check the size of the inside where the pipe could go as the only one I’ve found would have to be posted.
      Are there easy alternatives that I wouldn’t have to mod, or do intake sponges come in courser versions? (I haven’t checked).
       
      Any input would be appreciated!

      Hey guys, I’m really wanting to get freshwater crabs, and the only ones I’ve found are A. Lacustris and A. Laevis. I can only put them in a 110 L community tank for now, but may have another option in the future. The tank is stocked with a large school of ember tetras, some rocket killies, some endlers, some tangerine tiger shrimp, and a pair of apistogrammas. Rare aqua advised that A. Lacustris would likely be eaten by the apistos, so the obvious choice would be A. Laevis, because they’re larger... right? But I’m worried that they might predate upon my shrimp, so wanted to hear some advice and opinions from more people with experience keeping these crabs.
      Cheers!

      Blanch a couple of them. Let's see if we can get the shrimp to eat them.
    • Steensj2004
      Leaves added. Ordered the Oregano oil!Fingers crossed!!
    • jayc
      Yes, it is external. That's why I suggested carvocrol. It will work both internally and externally.  The oil if soak in food will be eaten to treat internal bacteria. Add some diluted oil into the water column for external treatments. Doses can be found in the Disease and Diagnostics post.   Yes. But it's not like using carvocrol oil. Oregano leaves just aid in the process of using carvocrol oil.   Give it 3 days after treatment. And note: you might want to add a second dose 2-3 days after the first. So wait until you finish all repeat doses of carvocrol oil before adding the filters back in.    In case you didn't pick it up. The source of the info from the site you posted is our very own Diseases and Diagnostics post (see the disclaimer section in the link you provided).  The info here is more up to date. You will need to treat the whole tank with Carvocrol oil, if you have a bacterial infection. Just save as much beneficial bacteria as you can before adding the oil. Carvocrol oil is very soluble, so it will mix in the water well.    Carvocrol oil isn't cheap, so hopefully we are treating the right ailment. Assuming it is bacterial in nature and not a water parameter issue. As I said, the pictures provided were too low in resolution. Good luck.

      I looked at the one here following the original site I posted. I am unable to quarantine to use oregano oil. And isn’t the bacterial shell disease external. It would be nice to attack both.... If it were your tank, how would you attack this? I feel more confident that it is, at least in part, the chitinolytic disease.    I could remove the HOB and one of the sponge filter sponges. The sponge I can put into the smaller 5 gallon with the fish to keep it seasoned, while the HOB can simply be turned off. How long would I then wait on the oregano oil to work before adding the filter media’s back in? Hey, I just thought about Something.... I have some organic Greek  oregano growing right now in my herb garden. Would those leaves work, and can I add the leaves without killing the filter bacteria in the tank?  
    • jayc
      LOL. Did you read the article properly?🙁 Under the Disclaimer - who is the author?     The info I give you is much more up to date than these other sites who have taken a snapshot of the evolving field of treatment for shrimp diseases. I warned those websites, that they need to ensure they maintain the content, as I keep updating the Disease & Diagnostics post. But alas, they copy it once and never remember to return to update it. So our own Disease and Diagnostics post is the source and is actively maintained by me.  Carvacrol (aka Oregano oil) will treat bacteria of various types. Chitinolytic disease is just another form of bacteria. Oregano oil when added to food will treat bacteria internally. Oregano oil added to the water will treat bacteria externally, like on the shell/carapace, like in the case of Chitinolytic disease. But take caution with filter bacteria, as with any treatment for bacteria will also impact beneficial filter bacteria. You might want to remove half the media and keep in another tank, just in case. If you can get fresh Oregano leaves, add them into the tank and see if the shrimp will eat it. The Levamisole will work on external bacteria only. It would be very hard getting the shrimp to eat it to treat internal bacteria infections.
