在饲养观赏鱼时，水质控制和水温是至关重要的因素。不同品种和养殖密度的鱼类都有其独特的需求。对于家庭饲养观赏鱼来说，最好选择来自本地水域或同一温度带的鱼类。跟随有宠小编，我们将一起探索养鱼的小常识。

一、fish tank water temperature and fish life impact

Influence on life activities

In the suitable temperature range, fish can carry out their normal life activities. Within this range, their physiological processes function normally. Beyond it, they will perish.

Divide into 5 zones

The lethal low-temperature zone, sub-lethal low-temperature zone, suitable temperature zone, sub-lethal high-temperature zone, and lethal high-temperature zone exist in fish tanks. The sub-lethal zones are between the suitable and lethal temperature ranges.

Impact on growth

Fish's appetite strength, food digestion and absorption rate, growth rate, embryonic development time to maturity are all directly affected by water temperature.

Van't Hoff's law

Within the suitable temperature range when water temperatures rise so does a fish's body temperature; its physiological processes speed up accordingly (Van't Hoff's Law). Water temperatures influence the intensity of fish physiological activity.

Impact on reproduction

Water temperatures have a decisive impact on when fish reproduce; for example grass carp spawn at 18℃ above while large-scale mullet at below 12℃.

6., seasonal changes occur with them

A certain water temperature is a stimulus for spawning; spring spawners require warming up while autumn-winter spawners cooling down.

二、Temperature adaptation classification of aquatic animals

1., warm-water species:

These adapt to temperate waters where they thrive within 0℃ or more to 32-33℃ without difficulty.

2., cold-water species:

These adapt to polar or alpine waters where they survive well in lower temperatures but struggle beyond 20-22℃.

3., tropical regions:

These adapt to tropical environments requiring higher water temperatures thriving there.

4., according to climate adaptation:

Wide-range adaptable species tolerate wide thermal ranges often being warm-water species; narrow-range adaptable species have narrower thermal tolerance often being tropical/ cold-water species respectively.

三、Family Fish Tank Temperature Control Common Knowledge:

1.. Consider your environment,

Choose nearby or related regional aquatic organisms that suit local conditions for easier management & control over growing conditions for your pet-fish friends!

2.. Consider cost & time,

If you want hot-blooded fishes in frigid climates or vice versa! You'll need additional resources & effort creating an appropriate environment!

3.. Install heaters,

In aquariums install heating devices - summer: off winter: On maintain comfortable temps! As temps drop winter turns up heat!

4.. Seasonal adjustments adjust as needed:

During winter if too chilly (fish sluggish no appetite) keep temp steady/adjust as necessary ensure survival & health maintenance!
