? The clown fish may not be an adult. The clown fish raised by the family is usually an adult within one year. However, because of the different environment and ways of raising, the time for the clown fish to become an adult is also different. Some may mature in about one and a half years. So it's possible that the mismatch is not yet mature.
Clownfish mismatch may also be due to imperfect sex development, because when clownfish are born, they are sexless, their sex will first change to male, then to female, they will change sex according to their status, generally higher status will change to female, and lower status will remain male. So if they don't pair up for a long time, they may be determining the status of each person.
Clownfish Clownfish need to prepare a separate breeding tank for them before breeding. Breeding tank is more important for Clownfish, because breeding tank can make them feel more secure. If conditions permit, some shelter places can be set up in the breeding tank. Then the paired clownfish are put into the breeding tank, and they will pair and spawn on their own. After spawning, the female and male fish will guard the eggs together until the eggs hatch and can feed on their own, and they will stop taking care of the small fish.
