Water Pets

The other day I pulled out my dusty, old but classy aquarium from the basement. For several minutes, I stood there wondering if there are any interesting water pets I can put inside.

My extensive research led me to countless water pets that I could nurture at home. If you are searching for the same, allow my article to fill you in.

Non Fish Water Pets

The following are some of the available non-fish water pets:

Sea Monkey

Sea monkeys are a certain breed (hybrid breed) of brine shrimp by the name Artemia NYOS. Harold von Braunhut invented them in 1957.

These creatures spring to life immediately the magical dust touches water. What is for sure is that they happen to be a cult sensation.

Their tails resemble those of monkeys remotely. They are derived from crustaceans that undergo ‘cryptobiosis.’

The term ‘sea monkeys’ is simply a marketing term that handy in selling brine shrimp to children from advertisements in comic books.

The gap between the reality and drawings of these pets in the advertisements made many kids feel cheated.

Ghost Shrimp

Ghost shrimp are a darling of many as freshwater non-fish pets. Just like their name suggests, their near-transparent and unique bodies that make them not only fun but also cool to watch.

Many people buy them as a meal for other aquarium inhabitants. Another group of folks keeps them as water pets.

Two striking attributes about ghost shrimps are the fact that they are tiny and effortless to care for.

Having plenty of plants inside your tank is necessary if your ghost shrimp are to be happy. If you choose to keep them as pets, be prepared to watch them grow since they spawn in an aquarium environment.

Freshwater Snail

Many people keep freshwater snails as pets. You can keep them at stunning pets on their own or as cohabitants with fish.

Of the ones available, apple snails tend to be the most popular. Others are rabbit, nerite, Inca, and mystery snails.

What is likable among snails is the fact that they are low-maintenance. Their tanks need 10 – 25% water replacement every 2 – 4 weeks.

You must have a tight-fitting cover as snails tend to climb their tank or aquarium walls to escape if the opportunity presents itself.

Fire-Bellied Toad

Fire-bellied toads feature a typical toady green layer at the top. Underneath, these amphibians bring with them super-attractive orange-red tummies.

Since they are amphibians, they need a tank that provides both land and water. A 50-50 ratio should work just fine.

Make sure the tank does not have less than 25% water. Their bright coloring is an indication that they secrete toxins from their skin.

Although this shouldn’t pose any grave danger, the toxins contaminate the tank’s water that harms the toad. This means that the constant change of water is necessary.

Fire-Bellied Newt

Roughly 70% of your newt’s aquarium needs to be water. The remainder needs to comprise of sloping land area for newts to bask.

If you so desire, it is prudent to have a complete aquarium with floating cork bark. This is handy when it comes to helping your newts rest when need be.

Of great importance to note is the fact that a newt’s aquarium must have numerous aquatic logs, stones, and plants for purposes of hiding and climbing.

Similar to their fire-bellied toad cousins, these also secrete a toxin that might irritate your skin. Therefore, it is necessary to put on gloves when handling your newt.

Red-clawed Crab

You can keep countless crab species as aquarium pets. Of the numerous one available, the red-clawed crabs are the most popular choice.

Their personality and bold look are noticeable. The same is true to their aggressive pinching, meaning you need to minimize their handling.

Regarding the setup of their aquarium, red-clawed one can survive in fresh water for some time. However, brackish (somewhat salty water) is the best.

What you need to do is fill your aquarium with water that is several inches below the tank’s top. Also, remember to offer several perches on top of the waterline.

Finally, yet importantly, ensure your tank has a tight lid as these can be escape artists.

Red-Eared Slider Turtle

Turtles are highly popular non-fish pets. They come in different kinds.

On top of that, they demand diverse habitats just we learned earlier in this article.

The red-eared slider turtle stands out as the most popular semi-aquatic and aquatic pet turtle. It is also unique in the sense that this species has a name that is akin to a skateboarding trick.

The good thing about them is the fact that taking care of them is effortless. Although that is the case, their tank needs vigilant maintenance.

These species are semi-aquatic meaning that their tank needs to be changed frequently with clean and freshwater.

On top of that, you must also offer an area designated for ”basking” for your non-fish pets. This is handy when it comes to giving them a place to bask and get warm beneath a heat lamp.


These are an unusual-looking type of non-fish pets. The adorable Mexican salamanders boast the distinct ability to regenerate and heal.

When damaged, some experts have observed them regenerate and heal part of their brain. In some instances, a damaged limb might heal yet create an extra appendage thus resulting in a unique extra limb.

If you choose to keep these as your non-fish water pet, make sure your aquarium can handle roughly 20 gallons of water. That should be rough twice as big as your normal aquarium.

Due to their messy nature, they can soil water fast. Frequent replacement is necessary.

Freshwater Crayfish

It is important to note that crayfish are not cut out for community aquariums. When you keep them as pets alone, they make interesting and wonderful aquarium pets.

Today, over one hundred species of freshwater crayfish exist. Each variety has its requirements in terms of care and habitat.

Consequently, it is prudent that you do your extensive research before setting up your tank and/or bringing your pet home.

In general, most of them will survive in a tiny 5 – 10-gallon water tank. Larger tanks are necessary if you intend to have several pets of this nature.

Regular water changes are needed as these pets are messy eaters that tend to hide or hoard food.

Fresh Water Pets

Freshwater pets come in an array of sizes, colors, and shapes. The most popular ones are not only easy to care for but also colorful and bright.

Are you new to keeping freshwater pets or fishkeeping? If yes, then I highly recommend that you start slow.
