They learn to hold their breath under water.
They drink freshwater, and if they're a fish, they breathe saltwater or freshwater through their gills.
I have freshwater fish and i use aquarium salt. I put more in every time i do a water change
the answer depends on the fish species. if you didn't get the fish at a pet store, and found the fish in the ocean, keep it in saltwater. if not, use freshwater.
The density and pressure of saltwater is different from freshwater as is much of the bacterias and parasites. The acidity of the water is also of concern as the lower the PH the higher the acidity of the water. Saltwater being of a higher PH would not handle the lower PH of freshwater very well. Also if moving a freshwater fish to saltwater that fish will lose a great amount of water in it's body causing death and if the saltwater fish is moved to freshwater it will gain great amounts of water causing death.
Bony fish that live in freshwater typically face the challenge of excess water entering their bodies due to osmosis, as the surrounding water is less saline than their bodily fluids. To eliminate this excess water, they utilize specialized kidneys that excrete large volumes of dilute urine. Additionally, they actively absorb salts from their environment through their gills to help maintain osmotic balance. This combination of urinary excretion and salt uptake allows them to thrive in freshwater habitats.
It use to be under water
No, you use bait to get the fish out of the water......
yes
There are vitamin products made specifically for fish. I use Vita-Chem freshwater version for my freshwater fish. It is used to soak the fish food in before feeding them to the fish.
No! Well, that depends on what you mean by a fishbowl. If you literally mean a bowl with marbles and water like you would use for a goldfish or a betta, no. If you mean an aquarium with plants and an actual heater and filter, then yes. Hatchet fish make good freshwater aquarium fish.
Accidentally bought tropical fish water conditioner that contains aloe vera and I have a fresh water common goldfish, is it still safe to use on my goldfish ?
As long as you have a filter for your fish, it should be fine, just make sure you wait however long the instructions say for the filter, before you put the fish in.
