If they are livebearers, look for the gonopodium, which only the male has.
In swordtails, the male has a sword and the female doesn't.
If they are egglayers, then most of them cannot be identified by gender.

Guess no one looked back since you posted the species. You can only tell after your fish are at least a year old and are in spawning condition (typically spring, but can also happen in the fall with indoor fish). Theis link will show you photographs of what to look for: http://www.bristol-aquarists.org.uk/goldfish/info/sexing-fs.htm
The previous answers about the clawed frog eating the eggs are correct - and that once he's large enough compared to the size of the fish, he may eat them as well! African clawed frogs get to be about the size of a softball.
The goldfish also need a large tank to spawn - they should have at least a 20 gallon (the size they'll need for year-old fish). Depending on whether your fish are facnies (with a double tail) or commons, they should be allowed 10-20 gallons for each fish as adults. And if you don't want the eggs or fry to be eaten by the parents, you'll need a separate tank to put the eggs in once they've been fertilized.

"baybays"? Anyway it depends on the type of fish you've got. For instance, the common type like guppy, males are more colorful and have a bigger tail than females. I am not sure if the same applies to all types of fish. I suggest going to your local pet store like Petco or whatever place may be and ask someone there.
In regard to your frog there, yes, he might eat your baby fish.

Well kind of hard for the frog to eat them BEFORE they're born. But first, are your "fishies" live-bearers or egg layers???? Chances are good the frog would eat newly hatched or newborn fry (name for baby fish). Might even eat the eggs. Some fish are easy to distinguish sexes, others not. Not enough info here.

Male vs. Female: You can't always tell with some fish. In some fish, they all look the same. You may want to look up the type of fish on websites to see if they have pictures of male vs. female.
Frog: I'd take the frog out of the tank now and put it in a different tank. Frogs grow fast and end up eating everything else in the tank. We have had water frogs and had to keep them in their own separate tank with feeder fish or special reptile pellets.

It all depends on what type of fish you have. Some species are very easy to tell the difference because of coloration, and others are very tough.
And yes, your frogs will eat the eggs, and the other fish will eat the eggs too.

well first of all, you might want to keep the frog in a seperate tank if you think he will eat the eggs.
second of all, it depends on what species of fish you have. you may want to research your fish first. some species you can tell, and some species it's just a little harder. most of the time the females are darker in coloration. but It would be a little easier to tell you if I knew what species you had. Oh, well.
Hope this helps!! :-P

depends on the type fish you have. Usually, females are uglier colors, where as males are the brightest colors.
As for the frog, I had one and she ate shrimp, so I would assume that they would love little fish eggs!

It depends on what kind of fish you have. With some breeds the male will have brighter colors, with some there are spots... so hard to say.
