So I have a 45 gallon reef aquarium. My water parameters are all good with low nitrates and phos. Anyway I have had a bonded pair of clownfish for the past 5 months. One is a large 2” female Perculia Clownfish and the other is a smaller 1.5” occilaris clownfish (excuse my spelling). They have been bonded for the entire time I’ve had them since I bought them at the same time. Now recently, my female has turned aggressive towards my male clownfish to the point where he sits on the bottom on the tank on the opposite side. He still eats and everything but he won’t swim away from his area so I target feed him. He will not do a submissive shake in front of the female anymore when the female rushes him either. I have tried to acclimate the male in a Breeder box for the past 2 weeks inside the females territory to try and reestablish then into pairing again but to no avail. I don’t know what to do, someone help
