Watch the male. He could be sick. I've seen fish buddies/partners/etc turn on a weaker mate when somethings up - before we can see any signs of illness. BTW, I like to keep garlic and vitamins (Zoe) in my frozen feedings to help boost immune systems.
Had my clowns for 5 years maybe. The male started getting picked on. The female wouldn't let him feed either. Few days later, I noticed a cotton mouth thing going on with the male. Removed the male, treated and fixed the problem. Returned to the tank 2 weeks later or so, healthy. Boyfriend and girlfriend all over again.
