hello everyone. i have this False percula clown (Amphiprion ocellaris) in my 20gal nano. i have had him for about a year now. he is not that much bigger than the day i bought him. right now he is about 1 1/4" got a good measurement on him. he is eatting very good, swimming around being a normal clown. anyone know why he is staying so small? if i move him to my 150gal will he grow or stay small?
