Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
And if not, why is the water in the fish tank down an inch or so every morning? (And no, it doesn't leak) Just a thought for an early morning. :)

I'm trying to exercise daily. I was doing fairly well until I sprained my ankle 2 weeks ago but now I'm getting back on the horse. Today I walked over a mile with my arm weights that are about 22lbs total. I was out of shape and it was hard on my arms. I also did my 30 situps. I'm also going to drink a lot of water and try to eat healthy. I do tend to have a sweet tooth but I'm cutting...
Freshwater fish do not actively drink water, but absorb the water through their skin and gills. On the other hand, saltwater fish do actively drink sea water. Their gills process the water and take out the salt.
The salmon is an interesting example of a fish that lives in both fresh and salt water, and consequently, they have the characteristics of both types of fish. Salmon are born in fresh water, and migrate to the ocean. While living in the ocean, they drink saltwater by opening their mouth; their gills then rid their bodies of the salt and minerals. When the salmon enters freshwater streams to spawn, they stop drinking the water and instead absorb it through osmosis (osmosis means that the water passes through the cells of the fish's skin into its body).
Do fish drink water?

Dear Moped Bill:
Some fish drink the water they swim in, while others absorb it through osmosis. It just depends on whether the fish lives in freshwater or saltwater.
The MadSci Network explains that fish need to keep a certain concentration of salt in their bodies. Marine fish need to worry about preventing water loss, because they already get plenty of salt. They drink sea water, and their gills process the water but remove the salt. In fact, some saltwater fish lack properly functioning kidneys, in order to help avoid losing too much water.
Freshwater fish have the opposite problem: They need more salt. They absorb water through their skin and have effective ways of excreting excess liquid to maintain the salt they need.
Some fish have developed the ability to exist comfortably in both freshwater and saltwater -- the salmon and bull shark are notable examples. Bull sharks have been found far up the Mississippi and Amazon rivers, much to the surprise of people who believe sharks are found only in the salty, salty sea.
im sure you all do it!lol.
either way, fish absorbing or drinking, would take the same amount of water into thier bodies...right.
although why would you notice any difference in the volume of the water, if the fish is still surrounded by it?
it would evaporate right? i notice depending on the heat in the air my fish tank loses water, but i have to admit not quite to the extent of a whole inch!
its a bit of a worry... i agree with ruby ask your wife.LOL
my fish eat each others poo!
Fish pass water over their gills to get the oxygen out of the water. If have lights directly over the tank, that could evaporate the water but an inch of water over night thirsty mices?

Have you ever noticed your fish have a little string looking thing trailing behind them under their bottom fins? That is their waste. It will eventually break off in the current and does disolve into amonia, nitrates and nitrites which you remove with every water change. If you n ever changed your fishes water and didn't have a filter or protien skimmer, then algae and such would start to thrive on this negative water condition and would eventually kill your fish.
water changes = important!
