I like oscars but over the years, this is always the fish that a friend, family member or just random peoples house you may visit, they have the HUGE oscar and HUGE pacu in a 30 gallon tank, half filled with water, 3 green sides, heater broke from not being submerged in enough water, the filter dropping water from 20 inches above the water line so loud it drowns out the whole house, a turned over slime covered pirate ship and a hand full of marbles and quarters sitting on top of alge covered blue rocks.......oh, dont forget the 20 inch pleco. This made me kinda tired of oscars.
