Not successfully. Moving water will likely knock the eggs out of the nest. The water should be near still with only an airstone present.
yes
The developing fish inside the eggs eat the eggs.
Usually around 200 or so.

A Siamese fighting fish/betta? Yes! They cannot survive in salt water.
i think like 300 but sometimes even 500 eggs at a time!
I think the fish you are asking about is the Siamese Fighting fish AKA (Betta splendens). They are tropical fresh water fish.
Yes, most fish lay their eggs in water. This is because fish require water for their eggs to hatch and develop. The water helps protect the eggs and provides the necessary oxygen and nutrients for the developing embryos.
True.
Take them out of the tank and separate them. They'll most likely eat the babies.
