Why a Golden Arowana Bubbles at the Water Surface, and What to Do
A golden arowana blowing bubbles at the surface usually means low tank oxygen, poor water quality or wrong temperature, or simple indigestion. Fix low oxygen with a one-third water change and an air pump; keep temperature near 25°C and pH 6.5–7.0; for indigestion, fast the fish three days then feed easy foods like plants or cooked millet.
Goldfish Feeding Habits Across Life Stages
Goldfish feeding changes through three stages—larva, juvenile and adult. Matching diet to each stage's needs, keeping protein adequate and water warm (20–28°C) keeps fish healthy and colorful.
How do I care for a Pearl Monkey (Luohan) cichlid?
The Pearl Monkey Luohan likes warm water, 28-30C, and is sensitive to temperature swings, so keep the change under 2C when water changes; change 1/3 every 1-2 weeks. It eats brine shrimp, small fish, bloodworms, shrimp, and tubifex - not picky, but feed small and often, not to fullness. It needs ~10h light daily, ~4h lit.

A fish lying on the bottom on its side may lack oxygen; stop feeding, clean debris, change one-third of the water, and run an air pump. Wrong water temperature or big swings also cause it; keep temperature suitable and it usually recovers in two days. Watch for tail rot, skin sores, scale loss, or gill disease; if worsening, disinfect and treat specifically.
How to Care for a Golden Coin Turtle as a Beginner

Feed a varied omnivorous diet in moderation, keep the enclosure clean, and monitor the shell, eyes, and droppings for early signs of trouble.

Is the flame turtle a deep-water turtle?
The flame turtle is not a deep-water turtle, but it adapts well and can be kept in deep water if a basking platform is provided. Shallow water is better for health and growth. As a freshwater turtle it needs weekly water changes of one-third to one-half, with new water dechlorinated first.
