Do you need inspiration for cool fish names? If so, you have definitely come to the right place!

If you love fish, you have great taste. Recent surveys reveal our finned friends are now the third most popular pet choice in the nation.

In fact, an estimated 142 million pet fish are swimming around in aquariums all over the United States right now!

But that’s a lot of fish names to think of! Luckily, our cool fish names guide provides creative naming ideas for each new aquatic family member you choose to add to your tank!

So now, let’s dive into these curated lists of popular cool, cute, funny, unique and tough male and female fish names!

Cool Fish Names

Whether your pet fish of choice is a ferocious shark or a timid minnow, a saltwater lover or a freshwater dweller, you are naming a new family member. You want to be sure to pick out the perfect cool fish names to choose from.

This can be a tad bit nerve-wracking at first. Especially if the whole family has to agree unanimously on your choice of the new fish’s name!

For situations where no one in your family is willing to budge on their favorite fish names, consider giving your fish a first name AND a middle name. (Even if you end up with a fish named Mr. Wiggly Squiggly Splashypants Smith, at least you will know everyone is happy!)

Naming Tips

Here are a few extra fish naming tips we hope will be helpful as you ponder these lists of cool fish names and pick out your favorites:

  • Be sure your new fish name is short (or can be shortened) and easy to pronounce so even the youngest family members can say it easily.
  • If you want to name your new fish after a family member or friend, it is always nice to ask their permission first.
  • It can be smart to choose a name for your fish that you can readily share in mixed company of all ages.
  • If you get stuck, spend some time studying your fish’s unique species, colors and characteristics, such as yellow spots, flowing fins, or a zig-zag swimming pattern. This can give you extra naming inspiration.
  • Try not to put pressure on yourself to choose a new name right away. The more you relax as you watch and enjoy your new fish, the more likely you will be to land on the perfect name.

Fun Facts About Cool Fish

Every year, scientists and researchers discover new freshwater and saltwater fish species. No one is certain exactly how many different species of fish exist on the planet. Current estimates range from between 20,000 and 230,000 species!

In terms of size, known fish species can range from barely 8mm long (the itty bitty Paedocypris), to nearly 13m (the colossal whale shark). Of course, most fish species fall somewhere in between, and those are just the ones we know about!

The goldfish is no doubt the best-known and most recognized pet fish. But even goldfish enthusiasts often don’t realize there are actually hundreds of different species of goldfish. Or that they are related to the giant carp!

The priciest pet fish in the world today is the Asian Arowana, a fish that is so endangered and so prized it can (allegedly) fetch prices up to $300,000 on the underground international black market.
