Probably not except for a few, but I can guess. I know the fireclowns are about 34 and one Possum Wrasse is between 8 and 10.
I think the Perchlet is also 8 or 10. Most of the rest of them are about 5 as I got them when I moved here. I know the Sunburst Anthius are about 5. One 6 line may be 7 and the male mandarin is about 4 or 5. The rest of them are either gobies, bleenies or pipefish and they don't generally live past about 5 or 6 years so they are that or less. I think the Hippo Tang is only about 5.
