Freshwater fish do not drink water and obtain nearly all of their nutrients from their food. Saltwater fish do drink water and obtain many required trace nutrients from the water they drink.

Red streaks that appear on the body and in the fins in some of the fish in a tank are not caused by the fish changing color. This may indicate a low dissolved oxygen situation and immediate steps must be taken to correct it. Yellow Tangs in saltwater, and loaches, catfish and goldfish in freshwater will usually exhibit this symptom first.

Fish do sleep. Most fish don’t have “eyelids”. If the aquarium lights are left on for twenty-four hours a day, the fish will not sleep. They will become stressed, and eventually they’ll die.
