What happens if I change too much water for my flowerhorn?
Changing too much water destabilizes the tank, stresses the flowerhorn and can lower immunity and appetite, even causing illness or death. Change only 1/4 to 1/3 each time and match the new water's temperature, hardness and pH to the tank, then watch the fish for problems.
What to Keep in Mind When Changing Water for Your Arowana
Regular water changes are the first line of defense in keeping an arowana healthy, but doing it wrong can trigger refusal to eat, saprolegniasis, or cloudy eye. Proper care means pre-conditioning tap water to remove chlorine, changing only a small fraction at a time, keeping the flow gentle, avoiding feeding around the change, and watching the fish closely afterward.
What Fish Can Be Kept With an Arowana?
Arowanas are large, aggressive, territorial fish, so tank mates should be other big, fast swimmers such as parrot cichlids, oscars, datnoids, and rays. Use a tank large enough for each fish's territory, match water parameters (pH, hardness, temperature), and similar diets to avoid conflict.
What to Do When Your Arowana Develops Cloudy Eye?
Arowana cloudy eye is most often triggered by poor water quality, but sudden water changes or a bacterial eye infection can also cause it. Catching it early means simple water changes may cure it; advanced cases need the classic three methods — water change, salt, and heat — or antibiotics.
Favorable Conditions for Arowana Coloration
Good arowana color rests on five pillars: a pure bloodline, stable and clean water, a dark yet well-lit tank with combined top and side lighting, varied and nutritious feeding, and a balance of slow and fast growth. Patience is essential, because coloration is a long, gradual process.
Why Arowana Lose Color and the Risks of Forcing Quick Coloration
Arowana can fade because of heat, poor water quality, or long-term pigment feeds, and some fading is permanent. Many keepers chase rapid, vivid color, but the tricks used—restricted feeding, lower temperature, lower pH, reduced water flow—stunt the fish's growth and rob it of its natural stature. Balanced development matters more than looks.
Conditions That Keep an Arowana’s Appetite Strong
An arowana's appetite depends on stable clean water, a calm environment, healthy competition, and exercise. Here is how to keep it eating well.
Causes and Treatment of Scale Protrusion in Ornamental Fish
Common causes of scale protrusion in ornamental fish include poor water quality, parasite infection, and bacterial or fungal infection. Different causes require different treatments, but all involve improving water quality and appropriate medication. When the condition is caused by parasites, the fish can be cleaned with potassium permanganate solution and then treated with albendazole or mebendazole tablets as directed.
What Are the “Old Three” Fish-Keeping Remedies?
The "Old Three" is a classic, must-know technique every fish keeper should learn, and the go-to treatment when fish fall ill. It rests on three simple, low-stress steps: water change, raising the temperature, and adding salt. Regular water changes flush out waste, pathogens, and parasites to keep the tank clean. A modest temperature bump speeds up the fish's metabolism and boosts its immunity. Salt—used at a low concentration—shifts the water's osmotic pressure so bacteria struggle to enter the body and the fish's organs work less hard. Together these measures support recovery and protect your fish's long-term health.
Kohaku
The Kohaku is the representative variety of koi, beloved by many hobbyists, and is increasingly kept as a feng shui fish. It was first discovered between 1804 and 1829, and was gradually developed into its present form through selective breeding.
