Allanaspides hickmani - Hickman's pygmy mountain shrimp


John.

Recommended Posts

Had a search on here, no mentioned previously, so I thought I'd post this as it may interest some.

Has anyone heard of these before?

They look interesting, I'm aware they're under the threatened species act but I feel a breeding program between hobbyist's could only mean good things for the species?

Very interesting John and thankyou for posting this thread. It would be interesting to know about water parameters. I read in the info you supplied that they are found in peat beds. This opens up few things that come to mind straight away. Water softness, tannins and ph levels. 

Many years ago I was a member of the Avicultural Society and as a result of the hard work by members, a lot of endangered parrot and finch populations were able to be saved. I mention this because of your point about being a good thing for hobbyists. I can think of a few people straight away that are specialising in native shrimp on this forum and I'm sure would love to give these guys a go.

Do you have any further info about the regions in Tasmania that were mentioned in the pygmy shrimp PDF?

I found pH 4-5 on another site. I'll get those sites tomorrow when I get on the pc

Would love if we could get a breeding program for these guys. Guess they would love cold water?

wow they look really different to any other shrimp ive seen, they looks almost prehistoric!

Amazing little shrimp! Yes lodo, cold water is the problem in keeping many cool-temperate aquatics and especially those from mountainous areas. I haven't checked these out but i doubt that they have any tolerance to warmer conditions. 15 degrees C is the maximum tolerance of a few Victorian fish species, I imagine highland Tasmanian shrimp would need colder. 

Having looked at the links now, the species only occurs in the World Heritage area in SW Tas. It would be a serious crime if these were to be collected, and there's basically no chance of the average hobbyist keeping them alive anyway. If a breeding program was ever to occur it would be conducted by a government agency under strict control. 

There are other species from this ancient family (right, Buck!) in Tasmania and perhaps some of these are not endangered, occur in lowland areas of northern Tasmania and would be suitable for captivity. 

Great little shrimp anyway John, I had no idea about them until today. Thanks!

Can you imagine the difficulty of maintaining a population when you're restricted to crayfish burrows?  Its crazy!  I wonder what it is about them that prevents their survival in larger ponds/streams. Just not street smart enough to survive?

Yeah really cool little shrimp though. What I read indicated that they do occur in the flooded grassland between the burrows too...  so I guess they would cruise around in a tank like other shrimp do. Yeah I imagine they can't compete with competition from normal aquatic species in permanent water.

Might be predation pressure. There could be lots of eels or fish in the system if even the yabbies are hiding in burrows? :huh-:

This shrimp belongs to the very ancient Family of Syncaridae and while this genus occurs in only Tassie there are other species that occur in other states of eastern Aust. Most are quite tiny and blind, occuring in the hyporheos (interstitial spaces of the sediment) and in groundwater.

What else do you know about this group ura? Are there any of the larger species that are not endangered and protected? Any larger species from lowland environments?

No large ones as these, as far as I am aware.

@John. Did you end up getting a chance to get that other information?

They are definitely an interesting looking shrimp, at first glance remind me of a centipede lol

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?

      One interesting thing he mentioned was "Bacteria pressure", which I guess just means number of bacteria around.  Yet I see all these other videos from shrimpkeepers bragging about how much bacteria their filtering system holds. Also interesting is no mention of using anti-biotics to treat bacterial infection.  I think that has fallen out of favor recently.

      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.
