Notes on Keeping Goldfish in Winter
Winter's low temperature slows goldfish metabolism and weakens immunity, so adjust diet and water changes. Reduce feeding amount and frequency and lower change frequency. Avoid adding new fish in winter. Watch their condition for early signs; manage diet and water changes to lower illness risk.
Can You Feed Goldfish Rice?
Goldfish are omnivorous and can eat rice, but not too much. Rice is nutritionally one-sided and shouldn't be the staple; its starch can cause indigestion. Balance their diet—use goldfish pellets as staple, plus some plant/animal food and fruit. As ornamental fish, some live food also adds nutrition and color.
How to Choose Goldfish Food
Good goldfish food: pleasant smell, doesn't cloud water, not greasy, small size, doesn't swell in water, over 30% protein, and the fish like it. If fish won't eat it, even great food is useless, so preference is the basis. Good food smells fresh of shrimp/fish; bad smells of rot or sourness and is greasy from oil used to fake aroma.
How to Tell Good from Bad Goldfish Food
Judge food quality by color, smell, water stability, and size. Good pellets are dark yellow-brown, smell of soybean meal and fish meal, hold together in water, and aren't greasy. Greasy food uses oil-spraying, which harms fish. Smaller pellets are easier to eat and digest; imbalanced size wastes food and causes gut issues.
What to Know About Using Tap Water for Fish
Tap water contains chlorides harmful to fish. Let it stand or air 3 days so chlorine evaporates. Match its temperature to the tank to avoid shock; use a heater or ice pack if needed. Some areas' water has unsuitable hardness or pH—test with kits. Change 1/5–1/3 every 3 days to a week to keep stability.
Why Does My Goldfish Pass Long White Stool?
Long white stool is sometimes normal if no other signs. But indigestion or enteritis can cause it—judge by the situation. For indigestion, raise temperature, change water, and fast; it recovers soon. Feed on a fixed schedule to avoid overfeeding.
Why Hamster Poop Turns Green
Green hamster stool may come from newly introduced green vegetables such as spinach or lettuce - usually harmless; reduce them and watch the color recover. It can also signal indigestion, in which case ease raw produce and reintroduce slowly. Lastly, it may indicate chilling or infection; watch for lethargy, poor appetite, or rapid breathing and see a vet.
Why Arowana Refuse to Eat
Many factors cause arowana to refuse food - large water-quality swings, sudden environmental change, indigestion, a monotonous diet, or illness. Solutions differ by cause: change and stabilize the water, let the fish rest quietly, fast and regulate digestion, vary the diet, or treat the specific disease. Check water, environment, food, and health to find the cause.
Can a Broken Arowana Fin Recover?
Whether a broken arowana fin recovers depends on severity. If not fully severed, it usually regrows with clean water, steady temperature around 30C, and good nutrition, though slowly and less perfectly. Fully severed fins rarely recover. Keep water quality high and be patient through the long regrowth.
Why Do Arowana Get Sunken Eyes?
Arowana sunken eyes (eye recession) commonly come from internal organ inflammation, bacterial infection, or medication overdose. Treat by cause: antibiotics for internal inflammation, water changes and antibacterial baths for infection, and water changes plus warming for overdose. Keep water clean, warm, and oxygenated; mild cases recover in about a week.
