How to Tell Male and Female Silver Arowana Apart
Tell silver arowana sex by body size (males larger), longer pointed pelvic fins, a rounder belly on egg-bearing females, a larger head on mouthbrooding males, and the gill 'A' mark (males have a longer, irregular arrow). Females spawn from age 6, laying 200-300 eggs per quarter; males mouthbrood the fry.
Common Causes and Fixes for Arowana Underbite (Dou Zui)
An arowana underbite (dou zui) is a lower jaw longer than the upper, like an underbite in humans, and hurts its looks. It is congenital (genetic, shows at 20-25 cm) or acquired from oversized food, a too-small tank, frights, or normal male mouthbrooding. Mild cases improve with a bigger tank, timed feeding, calm surroundings, and smaller varied food; severe cases are hard to reverse.
How long is the breeding period of ornamental fish?
It varies by species; small fish mature at 28-50 days, large at 3-4 months, and some like arowana at 3-4 years. Before breeding, pair suitable fish and move them to a breeding tank to avoid conflict.
Orange Arowana
The Orange Arowana is a variety of Asian arowana kept by some as a feng shui fish. With a suitable environment and scientific care it is not difficult to keep. Fully grown fish reach about 90 cm, with orange-red gill covers and orange scales, and are the most affordable of the red arowana varieties.
Silver Arowana
The silver arowana (Osteoglossum bicirrhosum) is a large, dragon-shaped fish named for its silver scales; adults reach 90–100 cm. It needs a big covered tank, plenty of light, and a meat-based diet of shrimp, fish and insects.
What Types of Cleaner Fish Are There?
Cleaner fish are aquarium species that help keep the tank clean. Many fish fill this role—including the three-stripe corydoras, black-line flying fox, black molly, flying fox fish, gold sailfin pleco, eartheater cichlids, kissing gourami, rope fish, and plecostomus—consuming algae, devouring the biofilm and oil film on tank walls, and clearing leftover food from the bottom. Keeping them appropriately can effectively reduce water pollution. Because cleaner fish vary greatly in size, it is best to pair smaller cleaners with smaller fish and larger cleaners with larger fish.
Why Do Aquarium Fish Fight — and How to Stop It
Fish fight because of naturally aggressive breeds (bettas, piranhas, arowanas, flowerhorns), overcrowding, breeding rivalry, bad water (temp/pH swings), food competition, or wrong mixing. Prevent with isolation for bullies, hiding spots, lower density, careful water changes, enough food, and balanced sex ratios; treat injuries with warm clean water and an antibiotic or salt bath.
Common Natural Live Foods for Ornamental Fish
Natural live foods - bloodworms, shrimp, silkworm pupae, mealworms, brine shrimp, tubifex, superworms - boost color and activity but carry parasites and bacteria, so always clean and disinfect them before feeding. Choose by fish size and use in moderation.
