I was assigned a semester-long project for my animal companions class and because I love aquariums I've decided to breed fish. I currently have a 40 gallon tall aquarium and was wondering if I got 5 of the large angelfish from Petsmart if they'd pair off and breed before the semester ends. If not, what would be a good fish to breed? I know cichlids spawn often but I don't have the rockwork and hiding places needed for them or the cash to pay for it. I've already bred livebearers and was hoping for something new.
