sounds like a good mix, bound to be something he will gorge himself on. lol im not sure why i call all fish 'he' Oh... Im sure you know but make sure your lid is secure... A while ago a shop near me had an awesome ornate, around 16 inches long. i went in one day and it was gone. i asked after it and it had gotten out fo the tank and dried up on the floor. really was a crying shame! My tank lid is cut at each end for external filter pipes but i have cut rubber to fit snugly to the pipes so there si no gaps whatsoever
