If you have both a male and female in the tank and you see eggs, then it did lay them.
How old is your fish? Your fish may have laid eggs, After a fish has laid eggs it will pass on, one of my fantails died after it laid eggs :(
get the eggs out and put them in a separate tank because the fish will eat the eggs.
how do you tell if a box turtle laid eggs

The only way to relocate Angelfish eggs is to move whatever the eggs were laid on. Removing(scrapeing) the eggs from where the fish laid them will result in the death of the eggs. HTH
It varies depending on the type of fish. For many, female fish lay eggs. The eggs are fertilized by the male fish outside the body of the female after they are laid. The eggs grow into baby fish.
If you want them to live, you keep them in the water where they were laid.
actually, it depends on the type of fish and the type of frog that laid the eggs some fish die from eating frog eggs (e.g. catfish- poison dart frog)
It depends on how old it is, and how many it has laid before.
It all depends on what you want. In other words, if they are fish eggs do you want more of the same fish that are in the tank - and the same for snail eggs. The kinds of fish you have will tell you about the eggs and where they are found. Sclares (angel fish) deposit their eggs on the glass or a leaf. Cichlids usually drop their eggs into the sand. Siamese fish blow elaborate "egg nests" made of bubbles. A small gel-like patch on the side of the tank is usually snail eggs - unless you have a large snail such as a Mystery Snail.
I'm assuming you are referring to aquarium fish. The amount of eggs laid can vary greatly between species. Dozens can often be expected from most fish.
