How Many Shrimp Per Litre?

One of the most frequently asked questions in the hobby is arguably How many shrimp can I have in my tank? Although the query is rather straightforward, there are a few considerations to take into account when determining acceptable stocking levels. I’ll discuss the scientific technique rather than utilizing a rule of thumb approach.

In terms of growth performance, the study found that keeping 5–10 dwarf shrimp per gallon (about 4 liters) is the ideal shrimp density. The trials’ findings demonstrated that the shrimp’s final weight and size were decreased as shrimp density increased.

This article will provide comprehensive answers to all of your queries if you became inquisitive and wanted to learn more about shrimp density.

Per litre of water, how many red cherry shrimp are there?

Just curious as to how many shrimp should I put in the tank per liter of water.

Do you mean to say that the size of your tank is simply a litter? Because if that’s the case, your tank, which holds just 0.256 gallons, can only accommodate a small number of juveniles, whereas an adult requires at least a 2 gallon tank and numerous adults at least a 5 gallon tank.

Wow, thanks. That’s a little 50 gal with 30 shrimps, yet it seems quite bare when I picture it.

Or you might simply purchase a number at a time at various periods until you have a large number. But the expense will still be quite high.

That is a great offer, by the way. A few hundred Ghost Shrimp would cost more than $100 on eBay, and occasionally up to $200 or $300.

In actuality, 2-3 per liter or 10 per gallon can easily be handled in a mature tank with lots of surface area. Over 100 shrimp might be comfortably housed in a 10 gallon species-only shrimp tank.

I realize this is an old topic, but shrimp breed and produce young; buy a couple and let nature take care of the rest. If you purchase 100 shrimp and they all finally perish on you with young, perhaps conduct a Google search to find out what went wrong or seek assistance from your neighborhood aquarium club. There’s no shame in realizing you can correct errors, but if you continue to kill living things out of disregard because you believe you don’t need to learn anything, that’s BAD on you.


The main stocking recommendation I’ve constantly read was 10-15 per gallon, but I keep seeing that debunked. One person I recall expanded their colony from a 5 gallon to a 20 (I believe?) and ultimately moved over 500. If all you have are plants and shrimp, simply let them do their thing, and good luck!

500!!! The numbers are increasing! But I’m so happy that everyone seems to be saying, “Just leave them to it.” Mother Nature must be the wisest.

You can use the fact that you’re having such success with reproduction as justification for needing a new tank.

I have to admit that thought did cross my mind when I saw some stunning Jewel aquariums on sale last week. The only issue is that I already have three aquariums, two shrimp tanks, and one fish tank from prior “upgrades” and have a cupboard full of tanks. If my pastime grows any further, my partner has threatened to leave. I suppose I could always move him out instead (it is somewhat taking over the living room)!

HI In November, I started my 5-gallon tank with 6 plants because 15 of them died in the first week. Those 6 plants are already well into the hundreds! They supposedly manage their own population when congested, but I’m not sure since they simply keep doing it, lol. Due to the bladders that the plants brought, I added an assasin snail. I also have 4 ember tetras in the tank, and everyone is doing well. When I first began utilizing bacter ae, I noticed a significant population increase…

They are outstanding! I’d love to reach that number! And since it appears that my minI colony still has a very long way to go before reaching these kinds of numbers, I will most definitely stop worrying about my small population explosion (for the time being).

False Did

Hello, Lindy I understand that there can never be an exact science, but do you have a ballpark estimate of how many shrimp per liter you would consider “overcrowded”?

This is one of the questions posed to the contributors to “Breeders and Keepers,” Volume 1, where two breeders (Luck and Deppler) discuss how the social structure of shrimp only develops with larger colonies, whereas Pohler and Silva discuss how understocking is best, citing a ratio of 1 shrimp per 1-3 litres. According to Silva, difficulties usually begin in a 60 l tank with 200 shrimp, and 50 would be perfect.

What volume of water does a shrimp require?

Many aquarists want to know how many dwarf shrimp they can keep in 5, 10, or 20-gallon tanks, as I’ve already mentioned.

Fortunately, scientists provided a solution to this topic a few years ago. They conducted tests to examine the effects of density on the size, survival, and reproduction rate of dwarf shrimp (Neocaridina sp.).

Water characteristics and feeding rates were the same for all shrimp groups to rule out any variances. Researchers categorized dwarf shrimp into three primary groups:

  • shrimp in little clusters, 2.5 to a liter (about 10 shrimp per gallon).
  • shrimp in medium groupings, 5 to a liter (about 20 shrimp per gallon).
  • Shrimp in large groupings, 10 to a liter (about 40 shrimp per gallon).

These were the findings after 90 days of the experiments:

  • 15% more shrimp from small density groups than from medium density groups weighed.
  • Shrimp from medium-density groups typically weighed 30–35% more than shrimp from large-density groups.

By the time the trial was over, it was clear that shrimp in tiny density groups (10 shrimp per gallon) grew faster and weighed more.

How many shrimp fit in a tank that holds 10 liters?

The best aquarium or fish tank size for keeping freshwater shrimp is a 10-gallon aquarium, so let’s start there.

You can place up to 100 shrimp in a 10-gallon aquarium if you wish to keep them only as freshwater shrimp!

The recommended amount is 50 shrimp for a 10-gallon aquarium, or 5 shrimp per gallon of water, so that your shrimp have enough room and have a healthy, breathing aquarium.

The amount of shrimp you should retain per gallon of water depends on a few different things.

Which tank size is ideal for shrimp?

A shrimp tank is simple to set up. The procedure will be the same whether you wish to house Ghost Shrimp, Cherry Shrimp, Amano Shrimp, or even Crystal Red Shrimp. Hobbyists who want to create a shrimp tank typically have some prior experience with fish aquariums. Although helpful, this is not strictly required. The most crucial tasks in setting up the shrimp tank will be covered in the sections below.

The majority of aquatic shrimp species are valued for their diminutive size. Aquariums as tiny as 5 gallons can contain shrimp. However, it is more typical and advised to use 10 gallons. Like any aquarium, adding additional water can improve stability, which is crucial while caring for shrimp. Fish may not be as responsive to changes in water quality as shrimp. For novice shrimp lovers, the harder kinds of Ghost and Cherry shrimp are recommended.

Asking a few simple yet effective questions prior to setting up is crucial. Is there a nearby power outlet for electrical devices? Is there a nearby restroom or tap for water changes? In conclusion, be sure to give the location of your new shrimp tank serious consideration. In the presence of water, movement is particularly dangerous.

What proportion of shrimp should I add to my aquarium?

Can I put a certain number of shrimp in my aquarium? Per one gallon of water, 10 dwarf shrimp are allowed. For instance: Up to 100 dwarf shrimp COULD live in a 10 gallon tank. However, 5 shrimp per 1 gallon of water could be a fantastic place to start.

Having too many shrimp is possible.

Some people can only tolerate a certain amount of shrimp. However, consuming too many shrimp can result in allergic reactions that include hives, facial and body swelling, breathing difficulties, diarrhea, and even fainting.

Can I fit all the fish I want in a 30 liter tank?

If a heater was installed, a number of small, tropical fish may be kept in a BiOrb. Choose six neon tetras, five guppies, and several small, algae-eating catfish like Otocinclus if the water is heated to a constant 24C.

A community of real nano species like Boraras, Danio margaritatus, or Danio erythromicron would be fantastic if you want to venture off-piste. Even tiny Sparkling gourami species and Corydoras catfish species like Corydoras hastatus or pygmaeus exist. In a 30 liter BiOrb, you could keep 15 fish the size of a Zebra Danio or a colony of 20 tiny nano fish with a mature tank, adequate water quality, and regular maintenance.

Can shrimp clean my aquarium?

We were astonished by how quickly our newest species of tropical shrimp were snapped up after being released. We decided to write a blog post for all you fish keepers out there on how to care for shrimp after the success of our first shipment of shrimp. If you want to add something novel and entertaining to your tropical fish aquarium, freshwater shrimp are fantastic. Shrimp are fantastic for keeping your tank free of algae and food waste, and they are interesting to watch even though keeping them is completely different from keeping tropical fish. These friendly animals make for lively environments and are quite simple to take care of.

Should shrimp have a filter?

Should shrimp be filtered? It is generally advised that you cycle your shrimp tank completely before adding any animals because shrimp are extremely sensitive to ammonia and nitrite. This simply entails operating the filter long enough to establish a sufficient population of helpful bacteria that will maintain acceptable levels of ammonia and nitrite.

Do shrimp ponds require CO2?

Gases include carbon dioxide. It can dissolve in water and make a tank more acidic. The pH of your tank changes as a result of the elevated acidity. Because CO2 is essential to a planted tank, it is crucial to maintain the proper CO2 levels in a tank. Every plant requires CO2. This is because plants need CO2 for photosynthetic processes.

In general, the more CO2 you supply, the more carbon the plants can use during photosynthesis to produce energy (glucose/sugar). Plants might suffer or grow in an unnatural way when there is not enough CO2. Therefore, having too little CO2 in the tank can harm the plants there.

The dangers of too much CO2 for your fish, shrimp, snails, etc. They are able to choke. At the same time, algae growth will accelerate in a tank with insufficient CO2.

Note: The environment of the tank as a whole has a greater impact on algae growth than CO2 levels. Plants develop quickly and healthily when they are content and have access to sufficient food (CO2). As a result, in the tank, aquatic plants outcompete algae. Algae therefore prospers in the tank when the plants do not.

Is it simpler to maintain shrimp than fish?

Shrimp can be housed in smaller tanks or environments with a higher density of inhabitants because they are so little and produce less metabolic waste than fish. Having said that, I wouldn’t overdo it; it is better to do no more than 10 to 15 shrimp every five liters. Actually, the ideal tank size for breeding is 20 gallons. Neocaridina shrimp will frequently reproduce if they are comfortable (with a large enough baseline population, this will just happen without any particular effort on the owner’s side), and you will soon see your tank is filled with many little shrimplets. If you want any of the shrimplets to survive and mature into adults, you should put them in a shrimp-only tank or a tank with a lot of plants because almost any fish will eat them. In my highly forested high tech, I have a sizable breeding colony with a modest fish population.

Asia is the home of the neocaridina shrimp’s native shallow ponds. They benefit from not actually needing a heater as a result (as long as your house stays in the 65-80 F range throughout the year). My observations show that mine are most at ease and active between 70 and 76 F. According to my experience, they prefer rather soft, acidic water with a pH of 6.8 to 7.5, a GH of 4 to 6, and a lower KH. Despite these inclinations, they are typically able to adapt to most environments and can even survive in somewhat hard water (although I wouldn’t recommend it).

In many ways, shrimp are simpler to raise than fish, but they are considerably more sensitive to changes in the chemical of their water. Please keep in mind that they are extremely sensitive to copper and many other metals, and that excessive iron fertilization to produce red plants or copper-containing water supplements can quickly kill them. A full plant fertilizer’s tiny amount of iron is more than enough to produce the brightest red plants and shouldn’t harm your Neocaridina shrimp at low concentrations.
