Pet Fish



Keeping fish as pets is a popular choice for many people. If you don’t have a lot of space or time to care for another type of pet like a dog or cat, a fish could be an excellent option. With their lower maintenance, tranquil presence, and low cost of ownership fish can be a ‘starter pet’ for children and young adults, or a long term pet for anyone that prefers less lower ongoing responsibility. Fish are also often more affordable than keeping dogs, cats, or birds and pets. 

Advantages of Keeping Fish As Pets

There are many reasons to consider keeping fish as pets! Fish have many advantages compared to other pet types. 

  1. Fish are more quiet than other pets
  2. Fish are usually more affordable to purchase than traditional pets
  3. Fish are also usually more affordable to maintain than traditional pets
  4. Fish are lower maintenance than other pets. They do not form separation anxiety, destroy furniture, need to be let out to go to the bathroom, or have their tanks cleaned as often as other pets like reptiles and rodents.
  5. Pet fish can be beautiful to look at and provide a calming environment
  6. Pet fish do not need to be taken to the vet for shots or registered with local counties
  7. Keeping fish as pets can be a great way to build responsibility for younger or first time pet owners

Disadvantages Of Keeping Fish As Pets

Despite their advantages, there are also some drawbacks to keeping fish as pets. 

  1. Some fish, particularly exotic ones can be expensive. The Platinum Arowana can cost upwards of $400,000 for a single fish! Some angelfish can be $30,000 or more. 
  2. Going from basic to exotic fish can mean a huge increase in maintenance, tank size, cost, and attention. If you have a saltwater fish pet that means more robust filters, larger tanks, and more attention to maintaining Ph levels
  3. Fish do not provide the same companionship as other traditional pets like dogs or cats
  4. Some of the most fun and exotic fish to own may be endangered or threatened, and have been illegally caught in the wild. Keeping these fish as pets could contribute to ecosystem and species instability. 

Freshwater Fish Vs Saltwater Fish Pets: What You Need to Know

What is better, saltwater fish or freshwater fish as pets? It depends, but generally freshwater fish are more affordable and hardier, so they are the better starting point for most pet fish owners. If you have never owned fish before and are unfamiliar with the maintenance of a freshwater vs saltwater aquarium, stick with freshwater to start.

However saltwater fish has a wider range of very interesting and crazy fish types to choose from. If you are an experienced pet fish owner, are ready to move on to exotic fish types, and don’t mind the maintenance of a saltwater aquarium then saltwater fish as pets can be very fun! There are many more options for pet fish types, and some of them are much more colorful and fun to observe. 

Just remember that an aquarium must be one type, either freshwater or saltwater. You can not mix freshwater fish and saltwater fish in the same aquarium. One of the fish types, and maybe both, will likely die.

Freshwater Tank (Aquarium) Vs Saltwater Tank (Aquarium) 

Freshwater fish tanks are generally easier to maintain. They are less expensive than saltwater tanks. Freshwater tanks are usually glass or acrylic and are appropriate for pet fish like tetras, betta, and goldfish. Filtration systems are able to more easily operate within a freshwater tank. They do not need to be as robust and are usually more affordable that the systems required for saltwater tanks. You can also usually get away with a smaller tank size.

Saltwater tanks must almost always be larger than freshwater tanks and are therefore more expensive. When maintaining a saltwater tank you must balance Ph levels more carefully and choose a filtration system that supports your needs. There are three options for saltwater tank filtration

  • 1) mechanical
  • 2) Chemical
  • 3) Biological (live rock).

If you choose a live rock filtration system for a saltwater aquarium you will also need a protein skimmer to remove fish waste.
