what type of catfish can live in a 125 gal its whole life and can co-exist with a FL gar and an arrowna?
if you don't know anything then don't try to answer! a 125G is already too small for an Arowana to live for life!a redtail as a growout same with shovel nose and a tigrinis or a colombian shark
then how about the FLG, a standard tank for FLG is 180G and with the footprint at least 5'x2'!the 125 is a growout for the aro
