I got my RTC at about 4" roughly 4wks ago, and today i noticed he was getting a little too big for my 150 as there a lot of plants and wood, so i caught him out and hes now about 7"! I put him in my 180 and he went straight into a clay pipe which i had custom made at 6x3" and he was bigger than the tube! Thats like 3" growth in a month! I don't even feed that tank very often like once every 2 days!
My little boy is growing up ..... errrrrrr my son too!!!!
