I just got a 3 inch Chitala Ornata and was wondering if I could put him in my pond. Only because the tank I have him in also houses my 2 inch Indo datnoid. And the IT is constantly picking on the knife. The pond is 15x 12.5x 3 feet deep. Has a 7 inch RTC, two 5 inch ID sharks, 6 inch channel catfish, 5 inch red belly pacu, and 4 plecos. Pond is oval.
