My 2 clowns have been getting along great for 3 weeks now. No fighting, always swimming and eating with each other. But just last night at their dinner feeding, the male didn't eat. This morning he didn't eat also. The female is a pig, thankfully. The male looks fine, but he is laying near, sometimes on the bottom othe tank on his belly, only swimming up just a little. He's not breathing hard or even looks stressed. The female stays near him, only swimming up for food or just swims away for a moment then comes back near him. Is this normal at times for fish to not be interested in food? This morning he moved toward some food, but didn't eat it. It's just him and the female in a 75 gal. It's od because he doesn't look sick at all. He will turn around or move around a little, but won't leave that spot.
