IMO and only IMO I believe that clowns need a bigger tank than 10 gallons because they like to swim , also the wil grow fully to 3 - 4 inches , i always read that fish need 3 gallons of water per fish inch. BUT trial and error , if the clown looks stressed , bring him back to your LFS , but i would stay away from it if i were you , save money and heart ache , this is just IMO though others will say its fine . and im sure people have more expertise than me here , this site is so helpful; and the community here is awesome to , I consider all of you fellow hobbyists my friends i wish we could all plan a big convention :happy:
BTW nice tank setup also
