Thanks to everyone replying for the encouragement.
Nothing new fish wise in the tank this year (2014) except for me adding the Salminus franciscanus into it during January.
It was the one in the 56,700 litre which with the help of MFK members Dave, Kevin and my daughter divided into 3 compartments roughly 36,700/14,000 and 6,000 litres over the summer of 2013.
The dorado had been brutal in the 56k litre tank
and I placed it in an outside pond during the summer of 2013 then an inside 680 litre tank
and then a 1800 litre tank always by itself.
It seemed bored and was not eating well when I reluctantly moved it to this 196k litre tank.
