Wes sent me 4 in Aug 2015 too, so I think our fish are all from the same batch.  Siniperca shuatsi.  Two were tiny ~1".  They ran out of energy to even feed after the shipping.  One fed (offered small guppies) but died shortly thereafter too, maybe it was too exhausted to digest a super meal he had had.  
Only the fourth, biggest survived.  Learned to associate food with me and since then follows me like a puppy.  Got him onto live frogs (caught in my yard) first, then he started taking frozen baitfish in Sept 2015.  Grew quickly from the initial ~1.5" to ~4".  Then stopped eating well, would only eat every 4th or 5th offering and a loss smaller portion.  In part I think my water has been too soft, so I have been hardening it but yet to see an effect on this guy.
He appears stuck at ~5".  Quite an achievement OP's is nearing 1'!
