1. Climate and water conditions
Some freshwater fish live in climates where the temperature is cold all year round. These fish will drink warm water to help their bodies regulate their internal temperatures.
Other freshwater fish live in climates where the temperature varies throughout the year. These fish will drink colder water in the winter to help them stay cool and drink warm water in the summer to prevent them from getting too hot.
2. Type of Fish
There are three main types of fish: saltwater, freshwater, and brackish. Saltwater fish live in oceans and seas. These fish get most of their hydration from the water they swim in. Freshwater fish live in rivers, lakes, and ponds.
These fish drink more water than saltwater fish because they have to replace the water they lose from swimming. Brackish fish live in estuaries, which is a places where freshwater and saltwater mix together.
These fish drink a combination of fresh and saltwater, depending on the conditions in their environment.
3. Size of Fish
The size of a fish also affects how much water it needs to drink. Small fish generally drink more water than large fish because they have a higher surface area to volume ratio.
This means that small fish have more of their bodies exposed to the air, so they lose water through evaporation. Large fish have a lower surface area to volume ratio, so they don’t lose as much water through evaporation.
Do fish drink water when they eat?
Some fish drink water when they eat. Freshwater fish live in climates where the temperature varies, and they will drink colder water when they eat to help them stay cool. Saltwater and brackish fish do not need to drink water when they eat because they get the majority of their hydration from their food.
