I have had this Asian Red Tailed Catfish for a month now... in a 55, Him and the dovii are pretty small. Dovii is 4 inches,ARTC 5 inches. Anyways I saw a Red Tailed Catfish for $34.99, and he was 5 inches, would he get along with the asian red tailed cat? My Asian red tailed did take over the tank and chases the dovii, but the store manager said that if the red tailed cat is bigger then the Asian red tailed cat they will be fine? Do you think they will get along? Just asking you guys, $35 is alot for a little guy?
