I debated between these 2 when deciding my stocking list. Went with the Spotted Kole based on some reports of the Tomini being more aggressive than the Kole. Ive had the kole just over 1 yr and he gets along with all my fish except my LMB, since day one he harassed the LMB and never quit. I believe this finally took its toll on the LMB, He died yesterday. I feel the Kole kept him so hemmed up he couldn't get enough to eat and finally starved.
