Interesting input from YT comments:
2025-ws As far as I know, Albino is growing at a slow pace / But your Albino Welles catfish is growing very well / He seems very happy with his current life…
Fish-Story Thank you. But I've never known or read that albino animals grow to smaller sizes versus the normal colored kin. How do you know or learn this?
2025-ws I'm a member of Naver Cafe, a large tropical fish in Korea, and I learned it from many experts there. Generally, red-tailed catfish can grow up to 4.5 to 5 feet in large tanks, but albinos grow much slower compared to the same period. So albinos are valuable for ornamental purposes in Korea (because the tank is small). ..... I don't know if it gets smaller, but it "grows much slower than usual." Experts in Korea usually have tanks at home (1800 x 800 x 800), but those with large tanks have seen it up to 3600 x 1200 x 1000. ....... If you had a regular "wells catfish" and not an albino, it would have been much bigger.
Fish-Story Thank you. I've never had an albino RTC. I don't know anyone who had one long enough so that I could ask them about the growth. Them do seem to grow slower or smaller or both but I've no concrete examples of numbers.
2025-ws I asked domestic experts. In summary, it's a mutant, so it's very slow to grow.
