ok than i think ill just get the 225 for more fish also do you think its possible to put a red tail in my pond its about 800 gallons
Red tailed catfish? 800 gallons will most likely fit an rtc for a long while. But be wary of a couple things:
-anything smaller than the cat will eventually become prey.
-rtc can live for decades and eventually exceed 5'. Caring for one is quite an undertaking, quite a commitment, regardless of your ponds size.
