Ensure that there is periodic water change. Besides, water quality and temperature has to remain stable. In addition, if you are feeding live feed, it has to be disinfected first. [Top]

Have a small tank that is treated with anti bacterial solution. Place the live feed into the tank a few hours before feeding. [Top]

5) Is fish feed a better choice compared to live feed?
Ideally, you should have a combination of fish feed and live feed. No doubt, fish feed will be more economical. [Top]

6) Is there a recommended frequency in feeding the fish?
You should at least feed the fish twice a day. Make sure that the fish is full after each feeding. [Top]

7) I’m going away for a couple of days. Will the flower horn fish die of starvation?
It is not detrimental to the health of the fish. Just feed it as you would normally do before leaving. Do not overfeed, as the excess food will only dirty the water. In the event if you are planning on a longer trip, just purchased an auto feeder. [Top]

8) Should the aquarium lights be turned on the entire time?
It is best to have the lights turned on for at least six hours a day. This will help to keep the fish healthy and at the same time, projects its vibrant colors. The lights should be turned off when we go to bed. This will be the time for the fish to rest. [Top]

9) What type of background posters should we use for the aquarium?
There are lots of designs available. Do not use posters that have a dark background. Flower horn fish basically requires an atmosphere that is bright. The color of the fish will be vibrant when we use a bright colored background. [Top]

10) Why is the color of my flower horn fish dull?
Check the pH level of the water. It might be due to high acidity in the water. [Top]

11) Why does the forehead / nuchal hump of my flower horn small?
It is primary due to the breed of the particular flower horn fish. Improper atmosphere and feeding could be the causes too. [Top]

12) The flower horn fish that I had recently bought is very timid and dark in color. Is something wrong with my fish?
It is normal that the fish is timid and dark in color. Give it a couple more days, once it gets used to its new environment, the fish will be back to its old self. During the period of adjustment, feed the flower horn fish sparingly. Overfeeding or excess fish feed would deteriorate the water quality of the fish tank. The adjustment period of the flower horn would normally take around a week or two. [Top]

13) How can I tell the sex of the flower horn fish?
Generally, it will be easier to tell the sex of the fish when it reaches 4 inches in length. At this size, most female flower horn fish should be able to start laying eggs. The most accurate option to determine the sex of this fish is by looking at the anal pore of the fish. The male fish will have a V-shaped anal pore as compared to the female which has a U-shaped anal pore. Additionally, most female do not have a protruding nuchal hump. The body will tend to look smaller as compared to a male which have a fuller and wider body. [Top]

14) Can flower horn fish be kept in colder climate countries?
You most definitely can. All you need to do is add a water heater in the tank. [Top]

15) Why does my female flower horn fish eat all its eggs?
When threatened, the female fish will tend to eat its eggs. Thus, you should place the female in a secluded area where it feels safer. [Top]

16) What is the life span of flower horn fish?
There is no exact record of the life span of flower horn fish. But it should live at least 6 years. [Top]
