yes he is an Adonis.. i have had him about 5 years.. i would have to go back to my early posts of him to know.. maybe 4.5 would be more accurate...he has grown to be a foot in that time..i really don't see anymore additional growth happening.. just less white dots and chunky... eats everything and had a big tank with only synodontis and arow as tank mates.. so very strange how all i read about is how big they get.. unless there are several species of Adonis..
