When a fish is stationary in the water, it typically uses a combination of its fins and body position to maintain its balance and stability. It relies on its swim bladder to control buoyancy, allowing it to stay at a specific depth without expending much energy. The fish may also use its gills to respire while remaining still, and its sensory systems remain alert to detect predators or prey nearby. This behavior often helps the fish conserve energy or wait for suitable feeding opportunities.
My fish stop all the time, but I don't know what will happen if they stop for half an hour.
If the fish are fresh water fish the kidneys would not work. The fish would die.
They die
they will die
If chinstrap is a fish, then no. Fish actually don't sleep!
Fresh water fish survive just as well as fresh water fish. Maybe this question isn't the one that you actually meant to ask?
they drown
it would eventually shock the fish and kill them
the fish needs to be in warm water that is just right. then leave the fish alone in peace and it will be fine.(:
If by clear water you mean freshwater than the fish will have all sorts of problems. It will be more likely to get a disease, stress the fish out, weaken its immune system, and will kill the fish.
They die.
it dies
