Part 1: Learn About Betta Fish

First thing you need to do is learn about Betta fish. Their requirements, do’s and dont’s. Following are some points that you need to take into consideration.

Please be aware of what you are getting into before you buy a Betta fish.

Know that these fish can live up to 10 years under the proper care, so do your research before buying. The minimum size tank for a Betta fish is 2.5 gallons with a heater and filter. Please do not keep a Betta fish in a bowl; it is terrible for their health and is very small! Your Betta fish will not be happy or live as long.


Do a lot of initial background research

Research Betta

There is a good deal to know about Betta fish, even beyond the basics outlined below. In general, large box stores aren’t concerned in providing detailed information, unless you happen to strike a Betta enthusiast salesperson. As well as having the basic understanding of Betta outlined below, you might consider researching more details about Betta fish at our Betta Page. The information provided there will remain useful for you after purchase too.

Picking out your Betta fish

Here are few things to look for.

  • Look at the color. Is the Betta’s color bright and vivid, or is it very dull? Even if the Betta’s color is a little pale, it should shine nicely. Bettas come in a variety of colors, but blues and reds (dark colors in general) are most common, although sometimes they can be white with a pink or blue tint.
  • Does the Betta react to your movement at all? Does it swim around quickly when seeing you, or does it merely sit at the bottom and sulk? Don’t repeatedly tap the container, as doing so agitates the fish. Instead, try moving your finger back and forth in front of the Betta without aggravating it. Don’t be afraid to buy a somewhat docile Betta though; they generally have many encounters with other people during their day, and may simply be resting. The average Betta bought in a pet store has been bred to withstand a lot of the hassles of a pet’s lifestyle.
  • Are its fins in good status, or are they torn or otherwise damaged? Keep in mind that some breeds have intricate fins, so they might look slightly torn.
  • Are the Betta’s eyes in good shape? Do you see any odd lumps (parasites) on its body? If you see anything highly out of the ordinary, consider another Betta. (it would also be helpful to talk to a store employee)
  • Sometimes, the fish will choose you, not the other way around. If there is one Betta that you look at, set down, move on from it, but are drawn back to it repeatedly, consider buying it. Even if it is not completely healthy, buy the fish you feel connected to, rather than the healthiest one there. He will likely heal up once out of the tiny cup and gets a fresh start in warm, clean water.
