Liz if I remember correctly didn't your old pacu break their tank at some point? How are you going to house them this time? I'm also a huge fan and miss he pair I had a few years ago.
Soon to be on order ...........very big tank.. or stock tub {which i already have two} what happened to yours .i remember them..Mine were happy up until there was a fire from a short in the wire under their tank.. the heat from the fire caused the tank to blow.. i lost the pacu but african cichlid survived.. they were 8 years old ...
