A shrimp will eat both plants and animals, but especially love plankton, and they don’t care if they’re dead or alive which means a lot of waste will be devoured by them in the tank.

#3 You Can Fit Plenty In

You Can Fit Plenty In

There’s no specific number of shrimp that someone can keep, but it depends on the tank and its capacity, with some other things to keep in mind.

Most aquarium owners follow the rule of 25 shrimp per gallon as this will give them adequate space and also make room for breeding, which they love to do.

If you plan on having a larger shrimp colony, upsize the tank, with around 20 gallons of space you’ll have ample room to do this. The more the merrier when it comes to shrimp, so don’t be afraid to go large, or even dedicate an entire tank just to raising these amazing crustaceans.

#4 Some Are Nocturnal

Some Are Nocturnal

Just like some species of animals, there are certain species of shrimp that won’t come out in daylight either. These shrimp would rather hide away when the sun is out and only come out the play when the lights go down, but some people miss the value of them because of this fact.

One of the main benefits of these types of shrimp, including the popular peppermint shrimp, is that they love to eat the unwanted anemones that can cause harm in saltwater aquariums.

Other than that, they’ll be hiding out in caves and crevices during the night and then come out for dinner when you go to sleep.

#5 They Keep Your Tank Clean

They Keep Your Tank Clean

As discussed earlier, a shrimp is a good eater, and they’re not fussy about what they eat either. This means they’ll work hard at cleaning the tank without even realizing it so there’s less time you have to spend doing the job.

Not only do shrimp feast on other dead livestock but they love to eat algae, and will even strip it straight from the wall of the aquarium.

As one of the pestiest parts of aquarium ownership, having a few shrimp in your corner who can help you with cleaning makes them worth their weight in gold. 

#6 They’re Easy to Breed

They’re Easy to Breed

If you don’t want to buy a bunch of shrimp to start which, the good news is they’re easy to breed without doing anything else.

This is mainly helped by the fact that shrimp can carry their eggs underneath their body and are taken care of before they’re ready to hatch.

One of the easiest breeding shrimp is the cherry shrimp, and if you have just two of these in your tank, there’s a good chance you’ll eventually see more. You can even spot the eggs that the female carries after a certain point which is always fun to watch as well.

#7 They Can Molt

They Can Molt

If you’ve never owned shrimp before and decide to get some, you could be in for the shock of your life when you see what appears to be their dead body on the floor of the tank. Rest assured, your shrimp has not died, but rather molted as it goes through growth phases.

Shrimp are capable of shedding their skin and they do so regularly while they are young.

It’s normal for a shrimp to molt around once a week which means lots of empty shells in your tank to clean. To tell the difference between this shed skin and a genuine dead shrimp, a deceased one will be more pink in color than when it’s alive.

#8 Fish Love Them

Fish Love Them

Just because you have dreams of owning shrimp in your aquarium, doesn’t mean you have to give up on having fish as well. Shrimp get along with many types of fish and can coexist peacefully, having done so for millions of years in the real world.

Some of the more friendly fish that are better housemates for shrimp include Guppies, Ember Tetras, Sparkling Gourami, Pygmy Corydoras, and Celestial Pearl Danio.

Although these are better at getting along than others, things still do occur in nature, but you’re guaranteed a much more peaceful experience for the shrimp when you fill your tank with these.
