Do freshwater fish get thirsty?
by
You might be interested to know that the opposite happens in freshwater fish. Water flows into their body through osmosis, instead of out. This means they don’t generally need to drink – but they do have to pee a lot.
As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.
Where do freshwater fish get water from?
Fish absorb water through gills through the process of osmosis, essentially being their equivalent to drinking water.

Is it OK to put fish in tap water?
Municipal/Tap Water
Most municipalities treat drinking water with either chlorine or chloramine for disinfection purposes. Chlorine is extremely toxic to fish and needs to be completely removed before the water comes in contact with fish. Chloramine is chlorine bonded to ammonia, both of which are detrimental to fish.
Ordinary tap water is fine for filling up the aquarium as long as you let it sit for several days before adding fish (the chlorine in the tap water will kill the fish).
Do fish like when you tap the tank?
Tapping Scares Your Fish

Can I pour bottled water into a fish tank?
Bottled Water
Bottled water is typically either well water, filtered water or spring water. It may have gone through filters that remove some of its beneficial components, or it may have extra minerals that are unhealthy for fish. You would need to test and adjust it before using it in your tank.
Do fish tanks naturally lose water?
The water level of your aquarium will fluctuate. Most cases of dropping water levels are simply evaporation, usually caused by higher temperatures in warmer climates. If you have an open topped aquarium consider using an evaporation tray in summer to reduce water loss.

Aquarium fish do not need light and it is best that you turn it off during the night. Leaving the light on can cause stress to fish as they need a period of darkness to sleep. Too much light will cause algae to rapidly grow and make your tank look dirty. So the short answer is no, do not leave your lights on.
How do you tell a fish is happy?

Do fish ever get bored?
Fish-keepers sometimes see their pets ‘glass surfing’ – swimming repeatedly up and down the glass of the tank. This could be the aquatic equivalent of the pacing of a captive tiger that’s bored from a lack of stimulation. But the fish could also be stressed from an overcrowded or unfamiliar tank.
Can fish hear you talk?
Yes, fish can hear you talk!
Sounds that are created above water typically do not carry enough force to penetrate the surface tension of the water, so talking on the boat or loud noise may not affect fish as much as your fellow anglers may want you to think. Your voice is unlikely to spook or scare fish away.
Fish are attracted to certain sounds and vibrations and not to others. Certain types of music and sounds repel fish while others interest them. Music and other sounds can define the change in the way fish behave in the water, including their eating and swimming patterns.
How do I play with my fish?
Try giving your fish tunnels or nooks to hide in so it can play hide-and-seek. You can also put fake plants in the tank and add a mirror to the side of the tank to stimulate its brain. To keep your fish engaged, add new objects or move things around every month or so.

What makes a fish happy?
Re-create A Natural Environment
Recreating the natural habitat of the fish is one way of making it happy. Fish can be from salt or fresh water. For a freshwater fish, pebbles are added to the aquarium and some water movement introduced to create the feeling of a river.
Do fish get bored or lonely?
You might be surprised to learn that, no, they don’t. At least, not as far as we know. Based on everything we know about goldfish, it is very unlikely that goldfish feel loneliness. It’s normal to wonder whether your goldfish will get lonely if kept in a tank on their own.
