my daughters best friends mom just showed me pictures of her sisters fish tank. it is a 180 with a 2' long rtc with a 20-22" id shark, both fish have been in the 180 for 10 years 



they look to be very healthy, though obviously severly stunted, i never would have imagined they would live that long and be stunted that bad. amazing is the only thing i can come up with. that is one pair of resilient fish.
Thats lucky that they are still alive but I don't see them getting much older since the stunting process will take years off their lives for sure... at 10 years old both are young fish!
