The tiny Sexy Shrimp has enjoyed good popularity among marine hobbyists throughout the years. It is called the sexy shrimp due to the way it is constantly twirling its body even when stationary. They are a type of anemone shrimp that are normally found in association with anemones in the wild.

Curiously named Thor Amboinensis despite their size. Very small, they are well suited to nano and even pico aquariums. Like the Fire shrimp and the Cleaner Shrimp, the Sexy shrimp are commonly found throughout the Indo-Pacific where they are collected in large numbers for the trade. They are also relatively cheap as a result, making them very accessible to all saltwater tank enthusiasts.

Tank mate selection is important. Due to their small size, they are easily harrased and consumed by larger fish. Strictly no basslets, groupers or any other large carnivores. They do well with pygmy angels. Although i'd avoid housing them with large angels just incase.

Upon introduction and acclimation, they will seek out an anemone host. If one is not found they will make do with substitutes from a variety of corals. Mushrooms, Green star polyps, clove polyps are good candidates for a substitute host. The sexy shrimp is a social creature that does well in groups. I've personally kept them in groups of 5 with little friction. Though there may be some infighting now and again.

Sexy shrimp are omnivores that will eat anything meaty and some greens. I''ve noticed grazing from one end to another end of the tank on what seems like microalgae. But upon introducing a few pellets or a tasty morsel of some sort they head straight for it. They are cheap to feed because they are so small. Generally any kind of sinking pellet will do. The quality of said pellet is entirelyup to your discretion.

You can go cheap and pick up inexpensive pellets for a few bucks or offer them a high quality pellet brand like New Life Spectrum. As usual, variety is important so go ahead a feed them some frozen mysis shrimp once in a while. Curiously, in the overview i stated how sexy shrimp were mostly reef safe. This is because they have been known to feast on zoas. This behavior is seen in the wild with groups of sexy shrimp sometimes devouring their anemone host itself. So it is important to keep them well fed. One feeding per day.

Sexy Shrimp Breeding

The sexy shrimp has been bred in captivity successfully by hobbyists.

There does not seem to be much interest from large scale breeders due to the low sale price of the sexy shrimp.

Males are generally smaller and thinner. It is thought that males have a single white stripe on their abdomen.

Females are larger with a rounded abdomen area. They tend to have a broken white stripe unlike the males.

Pairing them is easy. Simply introduce a male and a female and wait.

Getting them to breed is just as simple. If they are well fed, they will spawn routinely in the aquarium.

This offers a great source of food to the other tank inhabitants. Larvae are fed newly hatched artemia. As they grow, they are trained on other prepared foods other than brine shrimp.

I'm thinking about getting a small group of these shrimp in my 10 gallon tank which is a FOWLR ( i only have one firefish in tank), and wondering if they need to be in a reef tank in order to live happily and heathly ?

Hi James, they'll do just fine in a FOWLR. A few sinking pellets a day and they're set. Very hardy shrimp.

hey i'm thinking in getting some for my Nano reef tank

and I'm wondering if they 'll do fine with my my fire shrimp and skunk cleaner?

Hi Tim, i personally have never kept sexies with much larger marine shrimp like the cleaners. I guess i'm not too comfortable with these 1/2 inch shrimp sharing a small aquarium with 2-3 inch cleaners. Having said that, i haven't read about any incident where a cleaner attacked and consumed a sexy.


James  6 years ago

Hey pirateFx, just wondering if sexy shrimp can handle low temperatures like 69 or 65 ?,reason i'm asking is that i'm going start a cold temp pico tank with an waratah sea anemone, plus I couldn't anyone site that could answer my quession.

Hi James. I don't know how they'd fare at those temps to be honest. But if i had to guess, probably not too well as they are found in tropical waters. Maybe you could try posting this question on Reefcentral.com?

What anemones can a sexy shrimp live in?


PirateFX profile image

PirateFX 6 years ago Author

Hi Sebastian. I've seen them hang out the base of carpet anemones before. They should be able to host most commonly available anemones in this manner. However, they don't need an anemone to do well in captivity.

Has anyone thought about keeping Sexy Shrimp with Bumble bee Sout Western Banded Gobies if any one knows where I could find some.

@timon - Aye, they certainly are. It wasn't until i got into the marine aquarium hobby that i truly appreciated the variety mother nature blessed upon us. They are so beautiful. And while small, they do their part.

does anyone think about housing a group of 10/15 in a 17gall?

tank mates would be:

a pair of yasha gobys with a pair of pistol shrimps,

a pair of porcelain crabs and a group of shoaling trimmas..

would i have any succes in keeping them??

and be able to breed?

Hi Roy, 15 sexy's in a 17g is a lot. Get something like 3-5 and you should be fine. They are very easy shrimp to keep and they pair up and breed readily in captivity. Raising the fry is another matter altogether.

Hi PirateFX,i am thinking about getting some sexy shrimp and was wondering how many you would recommend for a 80l tank. I also was wondering would they be ok with a Tang, Damsel, common clown fish,serpant starfish and hermit crabs?


PirateFX profile image

PirateFX 4 years ago Author

Hi Emma - Sorry for the late reply. With 80 liters you can easily have a nice group since they're tiny. Among the creatures you listed, i'd worry only about the serpent star and hermits. Although i can't imagine a hermit being fast enough to corner a sexy.

Thank you! Your page has been a great help!!

Hey PirateFX,

I love your hubs. We just upgraded from a 20g to a 125g. About a week before that, we bought one Sexy Shrimp to see how it would do. The main concern in the 20g was our pistol shrimp as it's over 1 1/2" now. We saw the Sexy Shrimp the day after then not again until late last week. I moved it to our new 125g, and it seems to be doing well.

It was about $30 at our favorite LFS, so we were hesitant. But it's been a wonderful addition, and we're thinking of getting more. Our 125g only has 1x maroon clown, 1x yellow-tail damsel, 1x bicolor blenny and the pistol shrimp with its Randall's prawn goby. Plus a couple of red-legged hermits, a couple turbos and two bumblebee snails. We're still light on livestock, and I've become fascinated by shrimp (due in part to your writing!).

I have a four part question:

1) About how many Sexies can/should we add (them breeding would be awesome),

2) should we get them an anemone (our 1 BTA is hogged by the maroon) & what kind (preferably reef safe),

3) how many cleaner shrimp (skunk/scarlet) should we add to this, and

4) what are your recommendations for larger, pretty fish that won't hurt the shrimp (and the cleaners will like)?

Sorry this is so large, but I don't want to screw up our expansion by creating a really expensive shrimp buffet.

Thanks,

George

Hi there. Seriously want a saltwater tank but so nervous about doing it wrong. I want to make sure everything is perfect (especially since I know it's not cheap). I haven't started purchasing anything because I want to make sure I do it right from the start. I ordered 2 books I'm going to read but wanted opinions from others that are pros in this hobby. I have 2 freshwater tanks a 5 and a 10 gallon. Love my tanks but I'm so fascinated with the saltwater shrimp I would love to have some to watch and take care of. Anyways, just want peoples thoughts, opinions and tips if you're willing to lend some help out to a wanna be saltwater shrimp owner :) Thank you!

Tammy,

Check out the forums and blogs on Reef Central. http://www.reefcentral.com/forums/index.php

There is a ton of useful information there on chemistry, livestock, equipment, etc., and you can ask questions. I have a blog on lighting and others have great blogs, too. http://www.reefcentral.com/forums/blog.php?b=517

I also recommend joining your local reef community. Several use Reef Central. For example, in Central Texas there's the Austin Reef Club (ARC) http://www.austinreefclub.com/

thank you so much! I will be looking into these things and doing lots and lots of research. Was at our aquarium store today for over an hour just watching the cleaner shrimp clean up one of the fish. So awesome :)
