My betta Poseidon hasn't been eating for 3 days. He's still active and his color looks fine. Water params: pH 7.0, ammonia 0, nitrite 0, nitrate 5. Should I be worried?
Bettas can be picky eaters. Try different food - frozen bloodworms usually work!
3 days is usually fine. Try fasting for another day then offer daphnia.
