ok guys, here he is when he was 20-22". since then i put him in my friends 180 gallon until i get another giant tank running again. he is an aggressive male who beat up 2 other sailfin plecos the same size. i guess 450 gallons isnt big enough for more than one pleco. i will take more pics soon. this is the tank which is 10 feet long. the silver dollars were around 6" long just for size comparison.
