Re: jack dempsey, oscar, south american red-tailed
You better have a big tank to move them to. Red-tails will grow to over a foot in less then a year. You also have to be careful with your equipment when it gets that size. They get curious and start eating inatimate objects ( i.e. heater clips, filter in/out puts, etc.) they are real cool though, don't get me wrong, i would have one no dought at all if i had a big tank, Around 200 gallons or so.
