Spawning most species of Cyprinidae is not easy in an aquarium. Your best bet if you have space in your garage or patio is to buy a large tub and try to breed them in there. Then you can allow them to go through the natural seasonal changes that trigger them to spawn.
This can be done in an aquarium but is a real trick for a beginner. I've spawned a number of fish in aquariums but most are not easy to accomplish. In outdoor tubs I have gotten numerous species to spawn very easily. Just feed them, keep the water clean and they will do the rest...
