Hello sir, I had bought flowerhorn of about 2 inch size and had hump as per it sizeduring that time itself. However its been almost two months now my flowerhorn hardly response to my fingers. It keeps going below the filter all the time. It’s eating well and comes to surface of water as soon as I give him food. Tank size is good about 75 gallon but still is scared. As I show him shrimp it starts coming to the tank and even chases it but rest of time it gets scared.  The size has also grown to 3 inches but still is scared  How do I get flowerhorn more active and response to my finger movements.
