I bought my Oscar when it was full size. It has been a year since that. My Oscar did have columnaris about 8 months ago. He did make a full recovery. I change the water 1-3 times a week. Each week I will take 30-60% of the aquariums water out and replace it. I have 1 empoer 400 running. The tank is probily 5 out of ten in water conditions(The water is avrage quality). It is a 75 gallon 4 ft aquarium. He is genarely boring and scared compared to my old Oscars and is scared of evrything I do. He does eat though. Can you please tell me what to do to train him? Thanks!!!!
