i have a pink kissing fish now do they drink water because my does she goes near the filter and ****s up the freash water from the filter as it is returning to the tank from the filter thank you for your time

It's kinda hard for me to explain the process but I will try. All fish need to drink water like all other animals. Here is an example that was taught to us in class...(From my notes)

Osmosis is the movement of a liquid through a semipermeable membrane. The liquid moves from areas of low solute concentration to an area of high solute concentration. The flow continues until the concentrations are equal on both sides of the membrane. (The liquids move, not the solute)

Sal****er fish are in a water environment that is saltier than their body. Osmosis draws water through their skin out of their body. Sal****er fish need to drink water to replenish this constant loss.

Freshwater fish have a body that is saltier than their surrounding freshwater. Osmosis draws water through their skin (membrane) into their bodies. Freshwater fish do not need to drink additional water.


This is another reason it is good to always clean your tanks... fish not only drink the water but they breath through it as well..taking in the oxygen and filtering through their gills.
