I just reserved a 3" RTC on the phone with my LFS and I'm picking up a 150g this weekend and I was gonna put the RTC with 2-3 Siamese Tiger Dats. And I was wondering how long I could keep my RTC with this stocking, The reason I got the RTC is I need some extra $$$ to get a Jardini for the 150g so I'm gonna trade him in when he get's huge. How much do you think I could get for a 15" or 18" RTC? If I cannot get a good deal with my LFS I can always go to the marketplace on here and I know someone with a pond will most likely pay atleast $80.
