First I would like to say hellow, and congrats to a cool site. I need some help from someone in the Northern Ohio area that could take a TSN off my hands. I have went from wild fish ( bass,pike,trout,catfish ) to africans, to discus, to a reef with fish, back to discus, then angles, to my current stock of one Tiger Oscar that I have had for two months. In my quest to find a cool cat to go with the "O" I came across a TSN and bought him with out researching the needs of the fish. My 75 is going to be WAY to small, he is a really cool fish about 6"-7" long and eats well. I sure would like to find a good home for him. That being said once he is in his new home can you suggest a cat that is on the same lines but wil be OK in a 75 and hold his own with the "O".
