Alright, I've got a big project in school, which can be a very broad range of subjects. I want to be able to breed fish, so i need some information. For example a easily bred fish and all the procedures i need to follow. I have two options, using my 55 gallon tank or my five gallon. I also dont want to spend too much money. i heard rumor that you can successfully breed a livebearer with a goldfish to make it more durable. But i dont know. so everyone help me out. Any info would help.....peace
