Aw man, the monster fish LFS nearby me had 2 RTC's and one is about 3 feet plus long, adn they have sold it twice. It is in a huge square acrylic tank (8x4 or so?).
They also had a almost 3 foot long B.Micropolis (emperor cichlid?). Poor thing is gone now, but just recently it left, it used to just sit in the 300 something just chilling while a bunch of little mbuna (full grown, just little in comparison) swam around him.
And some monster oscars, and a RTGG that have been there since I first went there.
