How do fish suddenly appear in ponds?
Fish Are Already There Or local flooding causes lakes and rivers to overrun their shores, emptying into new valleys and low lying land, creating new ponds when the flood waters pull back. In either case, the pond forms with water already part of an existing ecosystem, complete with algae, bugs and fish.
How do fish spawn in a pond?
Spawning mats should be suspended approximately 6” beneath the surface of the water. The male fish will chase the females, leading up to the big moment when the female will rub her abdomen on the mat and release her eggs. The males will immediately fertilize the eggs.

Does every pond have fish?
Natural ponds often serve a wide range of animal species. However, not all ponds you see have fish in them as normally expected. There are a few subtle and no so subtle ways to find out if fish are in the water.
Why do fish chase each other around the pond?
The chase is a prelude to bumping the female around plants and rocks so the spawning process can take place. Even if you have two couples in your pond, the males may still compete with each other for both females.
How do fish get to isolated lakes?
Fish either reach new lakes and ponds through external help, or the creatures stay there, survive the period of drought, and then thrive again when water is plentiful.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Do fish get thirsty?
The answer is still no; as they live in water they probably don't take it in as a conscious response to seek out and drink water. Thirst is usually defined as a need or desire to drink water. It is unlikely that fish are responding to such a driving force.
Why are my fish swimming at the top of the pond?
A fish may linger near the surface because he's trying to breathe more easily. Remember, fish breathe dissolved oxygen—not oxygen that is already combined in the H2O molecule. Naturally, these dissolved oxygen levels tend to be higher near the surface, where interaction between air and water takes place.

Yes, fish can 'drown'–for lack of a better word. Though, it is better to think of it as a form of suffocation where oxygen levels are too low or the fish isn't able to properly pull oxygen from the water for one reason or another.
Does a fish fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart. For example, sand tiger sharks gulp air into their stomachs at the surface which they then discharge out the back door to attain a desired depth.

Can a fish survive in milk?
Fish have evolved over many millions of years to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecules. So, though skim milk is nine-tenths water, it still would be entirely insufficient to support a fish for long.

Can a fish get drunk?
That's right—fish get drunk, too! Working with Zebrafish—a common fish used in lab studies—researchers at NYU exposed fish to various environments of EtOH, technical-speak for alcohol.
