I think this is the right place to put questions on Fronts. I'm looking at getting a few of these and would appreciate if someone could chime in on an Approx. Growth rate for Juveniles and any other advice/information I can gather. I heard it rumored they will not start spawning until around 5yrs of age, is this correct? And would I be right in thinking that in the long run a minimum tank size is probably a 125 gallon?
