Nothing special, these already few months old it was purchase on 20th April. It is slow growth I intent to do it that way. It is not for commercial so I ensure they are not overfed otherwise it will be more blubber or fat than flesh.
Started with 150 in each of the return tank, not sure how many are left.
The feeder tank has remnant from last season fish and from this tank is what I use for table fish or give away to others.
