Great Fish Names
Naming a fish sounds simple until you are standing in front of the tank thinking, “Why is this harder than naming a puppy?” The good news is there are a few easy ways to land on a name that fits your fish’s look and personality, and even helps you remember their vibe or setup. Below are handy, ready-to-use fish name ideas, plus a few quick tips I share with pet families all the time.
Fast ways to pick the perfect name
1) Start with what you can see
Color, pattern, fin shape, and size can give you an instant short list. A goldfish might become Sunny or Marigold, while a fish with dramatic fins might be Cape, Ruffles, or Velvet.
2) Use behavior as a clue
Even small fish have “vibes.” Is your fish bold, shy, or constantly on the move? Names like Zippy, Shadow, Boss, or Wiggle often feel right within a day or two.
3) Keep it easy to say
Short names (one to two syllables) are easier for kids to remember and quicker for you to use in conversation. It sounds silly, but you will say the name a lot.

- Rio and Luna

A quick wellness note
A name is fun, but your fish’s environment is what keeps them thriving. If you are new to fishkeeping, here are a few evidence-based basics that prevent a lot of heartbreak:
- Cycle the tank before adding fish when possible. The goal is to build beneficial microbes that convert ammonia to nitrite and then nitrate.
- Use a water conditioner for tap water to neutralize chlorine and chloramine.
- Test the water regularly, especially in the first 4 to 8+ weeks while your tank is stabilizing.
- Avoid overfeeding. Tiny portions reduce waste and help keep water quality stable.
- Manage nitrate with routine water changes and appropriate stocking. Nitrate is less toxic than ammonia and nitrite, but it still builds up.
- Match the species to the setup. Some fish need heaters, some need schools, and some need more space than pet stores suggest.
If your fish is acting “off” (clamped fins, gasping at the surface, hiding more than usual), check water parameters first. Water quality issues are one of the most common causes of sudden fish stress.
As a vet assistant, I will add: this is general guidance, not a substitute for veterinary care. If you are seeing rapid decline, severe swelling, heavy breathing, or fast spreading spots, contact an aquatic veterinarian if you can.
Pick a final name in 60 seconds
- Choose a theme: color, personality, food, or space.
- Pick 5 names from the lists above.
- Say them out loud while watching your fish for a minute.
- Choose the one you keep repeating without trying.
And remember, it is totally okay to “try on” a name for a day. Fish are forgiving about name changes, and you deserve one that makes you smile every time you walk by the tank.
