i just wanted to share some real world experience about my rtc and my rtc x tsn with people that dont have any experience only what they have read. my personal experience i started my rtc off in my 20 gal high 5-6 months ago @ 2 inches, in one month he was 4" and got moved to my 55. 2 months later he was 8" and moved to my 90. now today 2-3 months later he was just over 12" long and a little over 3" wide actual body not counting his pectoral fins, and i had to move him into my 1200 gallon pond. i got my rtc x tsn 2 months ago @ 2 inches. same thing with the 20 gal. one month and it was 4 inches. only spent 1 month in the 55 as it is outgrowing my tsn by a long shot and moved to the 90 today between 5 and 6 inches long. if you think for any reason that you can house one of these fish in a 4' tank for any longer than 5-6 months comfortably you are out of your mind. please leave these fish to people that have 1k plus gallon tanks and ponds. any other personal experience posts would be greatly appreciated.
just last week a lady was reterning a rtc yll i was at the fish store it was about 6'' but big enough to eat most of her fish so i asked how much she wonted for it and she said you can have him hes in my 180g untill i build my diy project my pond armour just came in
