I have 2 22in Pacu's in a 125. Purchased a used all glass 240 to move them for $400. When I went to pick up the tank, there was a stand, 2 FX5's, 4ft Coralife, 5 300 watt heaters, 3 Whisper Air 300 pumps and a 25in RTC. The RTC was relocated into the 125 for 2 months, while I built a new stand from bloodwood flooring. Finished filling the tank last night and hope to move the the 3 monsters next weekend. For those who have small tanks, I'm waiting for the day that my RTC will outgrow my 240 (it isn't will he, but rather when). RTC's were featured on River Monsters where Jeremy Wade caught a 54 incher, then commented that it was still a baby.
