How big of a tank do I need to keep a Midas,pike,oscar all mature and a juvie gt and jaguar. The midas,pike and gt are in a 6` tank while the oscar and jag are in a 75 gallon.
are you wanting to keep them all together for life, or is this temporary? If this is a permanent setup you want to have then you're going to need something in the 240-ish range at least imo.
