No , none of that. I have a cat but he doesn't seem interested in any of my fishtanks anymore. The water parameters are good. 0 nitrite 0 ammonia, 20 or less nitrates, and the pH is at 7.0What are your water parameters? Have there been any lights flashing as of late or power outages? Is anyone moving quickly near the tank? Any other pets that might be agitating your Flowerhorn? Have they been bolder up until recently? It could be a flight or fight response. Beautiful Flowerhorn by the way!!
