Hey , just got home my new lil buddy , a silver aro ! he was shipped from a place and they forgot too call so it seems like hes been in the fish box for like 2-3 days and the water was pretty damn cold the poor fellah seemed kinda weak but it seems like hes already doing better in my tank , hes like 7-8 " id guess anyway how long does it usally take for this guys too start eating ? he seems abit thin and would hope to thicken him up and grow him up fast aswell so he doesnt become a snack for my Micro
