Nice clowns. I am a big fan and have had some of mine now for over 18 years. You defintely need a bigger tank than a 75. that is where most of mine started out. They are now in a 150 gal. and I am contemplating upsizing. I have 7 but also just picked up another 5 at 3-4 4 inch TL. They are in Q pending being added to my group. My largest fish are in the 10+ inch range.
