Hi guys and gals, I've been thinking of getting a Gar for my 450g. Wondering what kind of species and size would be suitable with a RTC? I've seen a 20" Spotted Gar at a LFS here and was thinking of rescuing him or should I pick up some smaller ones at 7-8"? My friend's LFS has a bunch of them at that size for sale but forgot which species was it. The 20" Gar at the other LFS is in a 72g and I really feel bad for it. Would it be ok with a RTC in the long run? My RTC is currently 13".
