Mosquito shrimp

I just got myself some Mosquito shrimps.

I'm wondering if it will cross with:
- Crystal Red shrimp
- Red Cherry shrimp
- Bee shrimp
- Tiger shrimp

Does anyone have any experience keep the mosquito shrimp ?
Could you share some information ?
Thanks.

You'll have to post at least a picture of a "Mosquito Shrimp." Otherwise nobody knows what you are talking about.

However, I did see what you guys call "Mosquito Shrimp" before and I can tell that they won't cross with any of the shrimp you mentioned for sure.

They don't have those shrimp here (yet), but there is a similar shrimp called Caridina gracilirostris ("red nose" shrimp).

Thanks Mustafa.

This is the picture.

I'm having difficulty keep them alive. They seem very sensitive.
I have 3 death out of a pack of 10.

My tank:
pH = 7.5
NO2 = < 0.3mg/L
NH4 = 0 mg/L
kH = 6
Temp = 28 deg C

What pH should I provide ? More on the soft side ?
The rest of my CRS, cherries are doing fine.

That looks like the one Rudolph that survived from my order from a company who looks like they are getting some neg press here :)

I like these shrimp :D Probably one of my favorite shrimp. They are more of a swimmer than a crawler when going from place to place.

I thought the common name of Rudolph Red-Nosed Shrimp were the same as the Mosquito Shrimp :?

Mustafa I am supprised you dont have this shrimp on the shrimp variety page

The reason I don't have this shrimp on my shrimp varieties page is because there are actually a whole bunch of shrimp from asia that have an elongated rostrum. Before their classification has been somewhat cleared up, I don't want to put them on the webpage.

I have one lone male Caridina gracilirostris running around in one of my tanks and a bunch of "long nose" shrimp that are even bigger than Amano/Yamato/Japonic (Caridina japonica) shrimp. They seem to be a subspecies of Caridina nilotica. So...I don't generally start describing shrimp before I am reasonably sure where they are from and what species they could be (or what species they might be related to).

As to their sensitivity...I don't think they are any more or less sensitive than most shrimp out there. They do tend to get shipped in huge numbers to the wholesalers, which already stresses them out. That might have been the first trigger.

Mustafa,

Is it a good bet that my mosquito shrimp prefer slightly acidic water ?
That of a lower pH ?

Does all shrimps like lower pH to breed (except Red Cherries) ?

You cannot generalize about shrimp and PH values. Some shrimp like lower PH and some can deal with higher PH better but will do ok at lower PH values, too. For example...bee shrimp and Crystal Red shirmp seem to be doing better in lower PH.

One of the mosquito shrimp died yesterday... :(
It turn whitish before it died.

Another is doing the same now... what should I do ?
My pH is 6.5 ~ 7.0.

The rest of the CRS and RCS are doing fine.
Maybe mosquito need higher pH ?

Anyone experience this before ?

I had them with PH of 7.2-7.8, and they still turned white and died. So I dont PH is the problem here.
Do you have any rocks? what kind of water conditioner are you using?

No, I didn't use any water conditional. I leave my tap water in a pail for a couple of days before use.

They are no rocks, just lots of gravel.
Does anyone know of any sucessful breeding... maybe in a German website ?

No breeding so far, but it should be as easy/difficult as breeding Caridina japonica, which has been done many times.

I had trouble with these (although I'm not sure my dozen or so are all the same species, I have one batch of what look like true rudolphs and "some others" in another tank) at the beginning. I had them in a well lit 15G with lots of plants and they kept dying, four in all. I put them in a 2 gal tank in my desk with two plants and no aeration. They stipped the piece if egeria i put in there in a matter of hours leaving only a stem. One of the things I noticed when I moved them was: no shrimp poop.

They were fresh imports right off the plane. I think now the things were starving. They lived in that tank for a month with only a few water changes and I put them back in their 15 and they're doing fine.

I have them i straight tapwater with nothing added. My water is VERY hard and moderatly alkaline. My bee shrimp don't seem to mind.

They are without a doubt may favorite shrimp. I'm not sure if this is because of their comical look, or elegant long body or more mobile habit. I just like them.
