a standard issue gibbeceps has been passed back and forth from me to my dad for at least 6 years, i think thoughwhen he went from a 55 to a 20 then to a 40 his growth was stunted, hasn't grown in about 3 yrs
I have a saltwater French Angel pushing 11 years. I bought him the size of a half dollar, he's now about 12' . I also have a Blue Damsel thats older than the Angel, dont know exactly how much though.
My friend had two pimelodius ornatus catfish. He got them i think abit over 20 yrs ago, but he sold them in the last month....
They were pretty cool looking, and i would estimate at 13 inches and 10 inches
