I've been avidly watching these little guys since receiving them yesterday, and I thought I'd make a new thread for the observations! Fist up some pics!large.DSC_0175.jpglarge.DSC_0170.jpglarge.DSC_0162.jpglarge.DSC_0158.jpglarge.DSC_0155.jpglarge.DSC_0152.jpglarge.DSC_0145.jpglarge.DSC_0135.jpg

Next, some interactions with shrimp. First up, a pair getting intimate (or failing to - looks like the male was just seeing if she was in the mood) while ignoring some nearby shrimp.

 

Next, a male getting territorial and chasing off a sunkist neo. Sorry about the lower quality - camera was set to low res accidentally. This movement is different from how they attack snails, so I think it's a territory issue rather than a hunting attempt. If you slow down the film you can see he raises his body and claws really high as though to look intimidating. But I'm not a crab expert so I dunno.

 

Next a shaky-cam quick-and-dirty video evidencing snail-eating prowess. Don't watch if you get motion sick!!

 

Next up, a rookie attempt at a close-up film. A bit shaky and focus is off, but you can see the female's cute face.

This video shows their normal behaviour around shrimp. Just completely ignoring them. A male walks past a group of shrimp having dinner.

 

The DAS in the video are adults. The Tangs just reached maturity a couple weeks ago so will probs get a bit bigger.

About half a dozen times I've seen them walk right through groups of shrimp without trying to eat them. This is including a group of shrimplets. That vid of the territorial lunge was the only sign of aggression I've seen.

In terms of food, so far I've seen them:

--> Eating a ton of snails.

--> Sifting through the substrate for morsels, with shrimp following and picking up the leftovers.

--> Chewing mulberry leaves.

--> Picking algae off moss. 

--> Eating Australian Blackworm Pellets - this is their favourite by far.

Last vid of the night. The females like to launch and try to swim, and this one makes a fairly pathetic attempt and lands in some shrimp.

Neo adults and shrimplets have got used to the crabs now. I saw them crawling on a bigger female as she walked around the tank.

Think if I have time enough, I will go to visit again my nerite spot wher i also found some crabs. That's a brackish water spot, but I hope the crabs will acllimate to the soft water.

snapped these during lunch break. You can see the shrimplets and juvies hanging around the crab to get the particles she throws up. Shrimp are blurry and out of focus though - no time to set up tripod!peaceful crab.jpgpeaceful crab 2.jpgpeaceful crab 3.jpg

Would they attack a nerite?

Nerites have extremely hard shells and a trapdoor they can close, and I imagine that would make them immune to the little crabs I've got. My larger ramshorn snails  (no trap door, softer shell) are surviving, but some have been attacked and maimed a bit. 

It really depends what kind of crabs you find. Some crabs may be strong enough to break into a nerite shell or fast enough to grab its soft body before it pulls the hatch shut.

These guys are still going really well. Shrimp crawl all over them now. I've even seen shrimp ride on their backs as they have territorial standoffs with each other (they never hurt each other - just kinda have a stare-down and wave their claws).

So a bit of an update on these guys.

I lost half of them when someone sprayed cleaning products around my desk T_T 

The remainder were tough bastards - they survived 3-4 more months whereas no shrimp made it more than a month after the incident. I miss them heaps. I'll likely have to move away from Australia for a few years sometime soon, but someday I'd love to make a species tank for these and breed them.

Hi mate, 

I'm sorry to hear about your crabs, 

But I was wondering if you had any survivors you would be happy to give away or sell as I'm super keen on getting some for my tank. 

Please contact me on here

Thanks

Hi Wulilions,

Sorry, no crabs at the moment sadly. I'm pretty sure a few people in victoria still breed them!!

      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!

      Don't buy one! If you already have an air pump, then you are 90% there equipment wise. Save that money for the BBS eggs. Google "DIY brine shrimp hatchery" and follow creation of one using a 2L soft drink bottle. It should include instruction on how to hatch the eggs too.    The first 2 weeks are critical. If they survive and eat BBS, then you can start introducing other foods.

      Try bee pollen. I use that to feed baby shrimps in rotation with other powdered foods. If you don't use it up, heck, it's good for humans to eat too! You can find many on ebay. Spirulina is good too, as Simon mentioned.

      Okay. Do I just buy some sort of kit or something, is it easy? I’ll get something set up over the weekend hopefully. Thanks for the heads up jayc!

      In the first few weeks BBS is essential. It's not the same as Frozen BBS. The wriggling movements of newly hatched BBS attracts them to eat. You can try frozen, but you'll find them ignoring it, and the leftovers will just rot.

      That's ok then, I thought you must have lost a lot or something! The dwarf puffers are interesting but you can't even keep snails with them as they eat anything that moves? The dwarf rasboras like similar conditions to TB shrimp. I will see what happens with next weeks delivery of shrimps first and decide from there? In theory I could keep both as it is a heavily planted tank so some baby shrimp should survive - if I even get any that is? One step at a time! Simon
