My Male flowerhorn I have discovered in the last few days, that its lips have about quadrupled in size, and he is acting like a gloomy gus sitting in a corner, not running around picking on the other fish, I dont know what this is or what to do, the temp looked like it was right about 76 degrees, so I pumped the heater up a bit, maybe I'll add another cuz its a single of the largest stealth heaters in a 75 gallon and it should be a lot warmer according to what i have it set at. any ideas anyone?
