Goldfish do rest. Sleeping is a concept that is different for the various species of life in our world. Many species do not require the type of sleep that humans require. Fish do REST but, if you are wondering if they run into a cave and float aimlessly while they sleep? No, fish do not sleep. They will slow down their metabolism and REST in a safe corner of their world. Also, fish activity becomes slower in the evening and when water temperatures drop when they are in safe places.\n\nAND:\n\nMost all fish spend time in an energy-saving state that can be called "rest", and we might even call their behavior "sleep", though it is probably \n\ndifferent than "sleep" in most land animals. Many fish, like Bass and perch, rest on or under logs at night. Coral reef fish active in the day, hide and rest \n\nin crevices and cracks in the reef to avoid being eaten at night. The resting behavior of fish is very different from their behavior the rest of the day. Many \n\nminnows, for example, which are very active in schools during the day, scatter and remain motionless in shallow water at night. Many fish "rest" or \n\n"sleep" during the day and are active at night instead, but almost all fish sleep. There are some animals that never stop swimming, like many species of\n\n\nshark, however, they HAVE to keep moving to push water through their mouths in order to breathe, and they may still sleep while moving,\n\n\nwe just don't know yet.

I couldn't possibly tell you about your fish.  However, I CAN tell you that your question is in the wrong section.  Try posting it in PETS>Fish...you might get a better response.  This section is for HUMAN illnesses and conditions!

I think your fish may have an infection of some sort (liver, intestines, etc)- this is what causes the bloating.  You can't really do anything about it.  I strongly suggest you check to pH in your tank and make sure it is appropriate for the fish that you have.  Are you filtering your water?  Are you cleaning the tank (removing waste which pollutes your fish's water/ air with harmful ammonia)? Are you taking the algae off?  Is the bubbler on overdrive?  Did you give enough time to let your tank set up before you put the fish inside the tank?  Where did you buy your fish [ if you bought them from Wal Mart or a corporate chain store- you made a mistake.  If you bought them from a local pet shop with lots of variety and all specimens were healthy- ask them why, and if they offer replacement]?All of these questions relate to the health of your fish.  Ask them on a daily basis with your next fish (Bubbles will probably head to that great fishtank in the sky soon). Check the link below on which setup applies to you and what you can do to keep a healthy tank.

They die because their skin is not waterproof like our is. When you put salt on them the dry salt causes water to flow straight out through the skin. That causes massive dehydration and they basically dies of thirst.\n\nIf you've ever had salt get into a cut or blister you have experienced the human equivalent. Because the skin is broken it is no longer waterproof and the salt causes a stinging sensation and localised tissue death.\n\nYou may want to think about how that feels next time you pour salt on a snail.

You would die.  Your neurons don’t exactly work very well without the sodium channels working.  Tetrodotoxin from the puffer fish is a nice example of what happens to ya when your sodium channels are blocked.

Every day, about 5 species die out. :-(

For aquariums?  Chlorine can be neutralized with sodium thiosulfate... you may be able to find this at a supply place, but not much more convenient than the regular aquarium stuff.  Ascorbic acid (vitamin c) will also do it, but i'm not sure alot of AA in the water is good- might promote fungus or something.  Don't gamble on the ick stuff, even a slight mis-dose or mis-formulation could result in dead fish.  You are basically making the water just toxic enough to kill the fungus without killing Cecil.

The Mad Scientist notes that if you tap on the tank before feeding your goldfish every day, the goldfish will eventually learn to look for food immediately after the tank-tapping. This kind of "classical conditioning" indicates goldfish have some memory. \n\nDr. Karl seconds that emotion, citing anecdotes of goldfish responding happily to their owner's faces, while hiding in their tiny castles when confronted with strangers. And while goldfish were domesticated in China roughly a thousand years ago, they still swim in schools, and thus have some learned social behavior. \n\nThe MythBusters TV show taught some goldfish to swim through a maze, noting that their time got better on each successive run. And an interesting response to the AnswerBag Forum describes goldfish memory as "selective" -- they have a general idea of what happened on a previous occasion, they're just not sure what. We empathize.

I cannot find anywhere where they actually say they found out what caused them to die.  One possibility was that sonar used by an american naval ship threw them off course.  \n\nI'm guessing...due to lack of interest in the results...that that might be the case because if it were anything else, I think the results would be posted everywhere!

Buy a goldfish and put it in the water cooler for all to see!

I doubt that anyone would really be able to answer that unless he or she just so happened to work there.  I suggest calling or e-mailing someone from the aquarium.

Osmosis would literally suck all the water out of the fish's body therefore dehydrating it.  It would be like taking a saltwater fish and putting it in freshwater or visa versa.  The fish may live briefly before it's metabolic pathways shut down due to lack of water.

Because they cant breathe in water. Drop one in a bucket of water and see how long it is before it dies.
