I am looking for an egglayer that is easy to breed...I have a 10 gallon, and have loads of experience with livebearers...I am really excited and cant wait for you experts to help me out...Please with the breed of fish you let me know about, please let me know about sexing, and that kind of stuff...you don't have to, but it would be nice...
I was going to say Convicts (Cichlasoma Negrofasciata) but your tank is only 10 G. They breed like rabbits and are easy to sex. If I recall the female has a reddish belly, but in your case I would steer clear of the Convicts in such a small tank. After the eggs hatch you'll have to separate the parents as the male will attack the female and eat the fry. Not sure how that would work in a 10G tank. BUT if you do have a larger tank available, I all but guarantee you can get Convicts to spawn!
Some of the best an deasiest egg layers are cichlids, they raise their own young, and there for they aren't as suseptible to and harm as with a type of fish that doesn't raise their own young. It is also true of the opposite too, some Cichlids are Verry hard to breed, especially the south american cichlids, (discus, angels, etc) some of the very easiest are indeed convicts, and they are very easy to get. Just make sure your pair is a compatible pair. If you are buying them from a store, watch them carefully and see if there is any "lirtation" between two fish, make sure also that they are not to males fighting over territory(look for the egg spots onb the tail for most African Cichlids) This goes for most Chichlids, so keep an eye out.
If you want to use a 10 gallon, a good choice might be kribensis. They make pretty good parents and are fun to watch escorting their fry around. They are also easy to sex.
I have a pair of Albino Cory's that breed like rabbits. I've never done a thing to promote breeding, they just do.
I dont know about sexes, but if you get 3 or 4, your odds are pretty good. They lay their eggs on the glass and on plants, and you can carefully scrape them off and put them in a bowl with some aeration, and bingo, 4 or 5 days later you've got dozens of baby corys.
i agree with zebra danios. goldfish are easy too if you had a much bigger tank. convicts will basically breed themselves and bettas are another good one but their young will take more work to raise.
most of the shelldwelling cichlids are very easy to raise but you never see the eggs because they are laid inside shells. I've had mine since April and just noticed fry a week ago and it appears there is more than one batch because I have several sizes swimming about. I have a 20 long with neolamprologus multifasciatus that are a very interesting bunch to watch. You just use a sand substrate with lots of shells and just add fish. I have 13 and it looks like I have about 15-20 fry minimum. they dig and move sand like little construction workers moving the shells into positions they like. they are by far the most interesting bunch to watch that I have. My tiger barbs are the most active but these have much more character. I always thought of hermit crabs when thinking of shelldwellers but I was way wrong. Some species hide most of the time when anyone's around the tank but others (like multi's) are out and about most of the time unless you rush the tank or stick something into the tank in which they will retreat for a while but come back out within a few seconds to see if the coast is clear.

I would say go with the cories, they're the easiest in my opinion. There's no special set-up such as gravel or anything like that, and all they require is a fresh cool water change once a week to get them going.
