  • Algae-Eating Shrimp.
  • Yamato Shrimp.

They were made famous by Takashi Amano, as a result of their credibility for controlling algae and also making sure your tanks are totally free of debris.

Behind the Cherry Shrimp, it is one of the most preferred freshwater Shrimp in the fishkeeping hobby.

Interestingly, since they are extremely tough to breed, the ones readily available to purchase are actually wild Shrimp.

They are sturdy shrimp that make them suitable for novices that want to try out invertebrates for the very first time.

They should be kept in at least a 10-gallon tank and can be kept in either a varieties-tank only or community tank.

The tank ought to be heavily planted and also include great deals of hiding areas for them.

The common behavior of the Amano Shrimp

They will hysterically run towards the food and speaking generally, the largest Shrimp has priority over the rest; you will surely see a ‘pecking order’ right here.

Beyond this, you will notice they spend most of their time foraging among the substratum and plants for remaining shrimp food and debris to eat.

Their Appearance

Amano Shrimp

Amano Shrimp is one out of the larger “dwarf shrimp”, and can grow up to a length of 2 inches. But when purchasing them, their size will generally be less than 1 inch.

They are easily identified by their huge transparent/greyish colored body.

You will see a lengthy line of red/brown or blue/grey dots running the length of their body form; this is how you identify their sex.

The dots coloring can vary substantially depending on their diet. Shrimp that heavily preyed on algae and various other greens will have a green color to their dots.

You will also notice that their tail (Uropod) is clear.

Lastly, you will certainly also see that they can mask and mix into your tank unbelievably well; they can be really difficult to discover when hiding!

Note: to locate the hidden shrimps, shine a spotlight into the storage tank in the evening in the direction of the substrate; the shrimp’s eyes will show and also radiate.

How to identify male from female Amano Shrimp

Unlike Cherry Shrimp, it’s really easy to recognize and differentiate between female and also male Amano Shrimp.

1.  First of all, the females tend to be bigger than the males.
2. You can observe the dots on their exoskeleton. The dots on females will resemble long dashes while those of males will be equally spaced-out dots.
3. Ultimately, the females always have a saddle (egg nest) beneath her stomach where she saves her eggs.

Lookalikes and imposters.

Within the aquarium trade, there are lots of lookalikes and also imposters. Whilst several of these imposters look basically similar, you can still tell the difference in their ability to clear out algae.

We have more than 200 different types of Caridina, so you can easily see why many various Shrimp obtain puzzled as true Caridina multidentata.

Due to the fact that they are generally lazy and do not make great algae cleansers; the real Amano Shrimp are relentless, this is the simplest way to recognize imposters. Imposters also often tend to be smaller sized.

Lastly, true Amano Shrimp require brackish water to reproduce but these imposters will breed in freshwater fish tanks.

It is extremely tough to visually recognize imposters.

Amano Shrimp Environment and Tank Conditions.


True Amano Shrimp are native to Asia, specifically Japan, China, and Taiwan. And they stay in large troupes within streams and freshwater rivers.
Interestingly though they do not constantly reside in freshwater. It’s only the grown-ups that live in freshwater.

Amano Shrimp tank mates.

To begin with, it’s essential to understand that the Amano Shrimp is generally seen as food, so you need to always exercise caution when including them in a tank.

They are exceptionally peaceful varieties and have no real ways to protect themselves.

Diet and feeding of Amano Fish

Amano Shrimp are known for feeding on algae if you didn’t already know.

They are also known as being among the finest cleanup teams in the hobby and will certainly feast on leftover food, plant debris, and algae.

They have actually also been understood to consume dead fish.
However, due to their reputation, some individuals think that they only need leftovers and algae to survive, this isn’t real.

They will constantly need their diet regimen supplementing. Obviously, the much more amounts of algae and particles in the tank for them to forage on, the less supplementing they will certainly need.

Since they are omnivores, they will certainly consume both meat and plant matter in the tank.

The core of their diet ought to consist of a top-quality pellet or algae wafer. You can also feed them on frozen foods, vegetables, and sinking pellets.

They will surely consume squash, zucchini, spinach, and cucumber among others.

Just keep in mind, however, that the vegetables must be blanched and do not leave in the tank for more than 1 hour because it will begin to infect their water.

In terms of frozen snacks, assume the usual: brine shrimp and bloodworms.

Just like Cherry Shrimp, you must stay clear of positioning anything with Copper into the tank; it is harmful to many invertebrates. Make sure to inspect the tags and labels as several medications and fish foods contain Copper.

Also, you must stay clear of putting them in a tank with black beard algae; they won’t consume this.

Amano Shrimp breeding

As said earlier, sexing them is very easy; however, trying to breed them is even easier. They are incredibly tough to mate and I’ve yet to learn through any individual that has actually successfully hatched the larvae and grow them into adults.

This is mainly because of the brackish water condition pointed out above. In the wild, the male will certainly fertilize the eggs and the female will carry them for around six weeks.

Throughout this moment, the female can commonly be seen wafting her tail so as to push oxygen over the eggs; just like the Cherry Shrimp.

At the 6 week mark, she will launch the larvae right into briny water. At the larvae stage, they need saltwater and when they develop and grow, they’ll need fresh water.

Keep in mind adults must not be put in brackish water; even a little exposure to salt can kill them.

It’s at this time you need to remove the grownups from the breeder tanks as you raise the salinity of the water.
Due to the minimal success stories of breeding them, we couldn’t find more information on reproducing the Amano Shrimp; this actually is just an undertaking for the most skilled fish keepers.

If you want to breed Shrimp, we would suggest you go for either the Cherry shrimp or Ghost Shrimp.

Among the greatest points, you need to take note of is copper. Stay clear of and totally avoid adding any copper-containing matter into the tank as this is highly destructive to all invertebrates.

If possible at all, avoid rapid pH or temperature drops, however, they are also surprisingly can withstand ammonia spikes.

They are most vulnerable when they molt; so you need to pay special attention to them. If they are well fed and feel secure, you should expect them to shed monthly.
