I went fishing here outside of Las Vegas, I am thinking of keeping a 30 inch channel cat. Currently i have a 300 gallon with 1 26''silver arowana, 4 8'' oscars , 8'' TSN x RTC, 8'' Two line pike, what do you think? I caught it this afternoon? Eventually after this summer I will be upgrading to an indoor pond please let me know what you think about introducing a wild caught into an established tank
