Fish Care & Information


Taking care of your betta requires responsibility. Betta fish is pretty resilient and inexpensive to purchase andthey can bring years of companionship and joy with low maintenance.

Before setting up your new habitat for your betta, it is very important to understand their nature. The female betta fish has a community-minded temperament and will generally share a tank with other female and non-aggressive fish. However male betta fish can also live successfully in community tanks, but a male should never be placed in an aquarium with another betta fish (male or female). Pet parents who want to buy a male betta fish are strongly urged to keep them in a tank separated from other bettas.

The absolute minimum tank size for a healthy betta is 2.5 gallons with the recommended size being 5 gallons or more. Larger tanks are easier to maintain nitrogen cycles and temperature and require less frequent cleanings. In the wild, the betta  lives in shallow oxygen-deficient streams, rice paddies, and puddles, but many of these areas are still expansive in water volume. Your betta needs room to swim around and places to hide. Never fill your tank to the maximum volume. Betta fish need access to the water’s surface to gulp air using their unique labyrinth organ. The labyrinth organ allows them to extract oxygen from the air and not just the water via their gills. This is why bettas don’t require air pumps. 


Upon receiving your new betta (fighting fish), you'll have to bear in mind they would be stressed from being transported. Hence, the acclimation process to their new home is of utmost importance.  

In normal scenarios where the fish arrives overnight as per usual, floating the unopened bag in the home tank for 15-30 minutes is generally enough. This is to prevent shock from a large temperature fluctuation.  Once that is done, remove the betta from the bag with a net and place into the home aquarium. Do not place any of the bagged water into your aquarium. Water from the bag will contain an excess of waste products produced whilst the fish was in transport. This can alter the water parameters of your home 


There are sometimes delays out of our control. If there is for whatever reason a delay in you receiving your fish please do not worry too much.  We do still need you to be available for the delivery due to it being livestock.


Fish are placed in plastic bags with water and oxygen before being placed in boxes. All fish are then put in a suitable insulated box with a heat pack if necessary. This should ensure minimal heat fluctuations and keep the fish safe until they arrive.
