in my own inamitable style i can top all previous posts and let you in to a well kept feeder secret (despite my feelings about feeder fish) mozambique tilapia breed very often and have a high success rate if seperated at birth from adults. 4 females can easily produce enough fish to feed about 3 feeders per day every day. they grow incredibly fast, i have bred platy commercially in the past and these tilapia grow about twice as fast. and thats just on a cheap flake. i have month old fry that are just under 10mm in size. if any UKguys want them i am about to begin sending some stock out for this very purpose. i will supply i male and 4 females delivered for £30 a cheap price for cheap regular food.
