Full grown ocellaris in 25 gallon?

[BristleWormHater]

Looking to add a longfin ocellaris. Someone at the lfs said a full grown clown will eventually need a bigger tank: Heres my tank dimensions L=25in W=23in H=11in. Thoughts?

I had a regular ocellaris (not designer) that was happy in a standard 30g for the first 18 years I had her. Of course total bioload is a factor. I typically only had 2-3 other fish in there at any time, the longest stretch was about 7 years of her, a flame hawk and a cherub Angel.
