What kind of shrimp are these

My lfs said that these are amanos but I'm not too sure now that they're under better lights. They don't have the markings. I don't really care what kind they are as long as they eat algae and won't reproduce.



The biggest is about an inch and the smaller one is about 2/3 inch. Smaller one is the one on top of the log.

The second picture looks more like Amanos than the first, the first picture does not look like they have the markings, like the little dots on the little guys, the second one...kind of. Unless they are like fat glass shrimp... I know of skinny ones all the times that I have seen them.

I think these are amanos - just very small ones. Markings on the sides will become more visible once they'll grow up.

Thanks guys! I was hoping they were too small to have the markings but I couldn't find anything on Google about it. I'll keep them for now and hope they survive and grow up. I only got them today but they started foraging right away after I acclimated them. They're both still alive after 12 hours so hopefully they'll keep going.

Caridina sp. that are *NOT* amanos. For the most part, they are being sold at Petco as amanos. Only seen one so far at an LFS (well, not local to me... but not a chain store, either)

True amanos are more slender and less "sparkly". (these guys can be "sparkly" - they are more dotted than amanos) Some of these do turn brown.

I do have a couple of comparison photos but not sure where one of them is ATM. (either lost on my phone or on a computer) Here's the one that was at an LFS in tank with amanos. She is the obviously brown/"striped" shrimp on the filter.





Plenty of other people are picking up these guys as well.... mostly from Petco, too. They also breed "like" amanos, but I do not know what the preferred salinity is for these guys. You can view more pictures of this species (whatever it is) in the following thread.

Are they workhorses like true amanos?

Ill have to take some photos of my amanos when I get home (if they cooperate). I have 3 that look like the standard amano but one big ol thing that is that brownish color without any dots on the side that I can see.

It eats and forages like the amanos, could very well be one not sure.

Whatever they are they did a good job de-browning my wisteria over night. The tips of the leaves were starting to get covered. My snail is too big to clean the plants I have.

Why the site turned my pic sideways...no idea

I honestly have a hard time growing algae... even when I literally leave the lights on 24/7 and overdose with ferts and stuff... no CO2. The best algae I can grow in a tank is the green algae that grows on the glass. I can't even get a "healthy" green covering of it, either....

Quite possible. I've only seen one turn completely brown, but I think she's faded back to a slightly transparent brown color... only in pictures though. Mine range from translucent (like OP) to the brownish hue... still translucent. In store, they've also been red and blue hued, or even a white opaque. (certain death in other shrimp species, dunno about these guys?)

Well she/he just molted last night and was out and about this afternoon so took a pic. Guess its a regular amano, just pretty big and turns a darker brown before molting. Still not sure as it doesnt look like any of the other amanos Ive got.

That's a caridina babaluti you got there most likely. Rainbow type probably and they'll breed in freshwater.

Same species as the "not-amanos"!!! Here's one thread where you can browse pictures of some others.

I thought so, too... or, well, I thought they were Malaya/Malayan. However, offspring have not survived in freshwater... in fact, they survived longer in saltwater than they did in freshwater. Have not been successful raising them to adult-hood, yet.


One shrimp expert (Chris Lukhaup) says they are Caridina villadolidi, another (Silane Dilwyn Tng) says they are Caridina formosae and a third person is saying Caridina typus.

Picked up a few more of these guys (I think) at petco. They whole tank of "amanos" were or atleast looked like the not-amanos. There were maybe 2 or 3 out of the tank that looked like classic amanos.

May grab a few more as I need a algae crew in my 40B but not sure yet.

The males of this species can look a lot more like amanos than the females do... but depending on the batch, Petco can have both species in the tank. As far as I can tell, they wont breed together, so although they are similar in appearances, they are completely separate species.
