Just my experience , with Tilapia . Wherever roots of land plants extended out of bank , trees , etc , Tilapia as small as 1" , by the hundreds would be sucking up and down these roots removing FA. Anything in the pond that had FA anchored to it , was cleaned promptly by small to medium Tilapia. The growing from Fry to Fingerling , to sexually mature was not wasted for removing FA. May have been the variety of Tilapia, the species of FA or other variable , but 3 years out of 3 , my Tilapia ate FA reliably at all visible ages of Tilapia. 1st year , an all white Tilapia From Moore's , 2nd year , a greenish Tilapia , from Moore.s , 3rd year a beautiful golden Tilapia from Harbins in Okla. All worked great , all delicious when scooped out of shallows the 3rd week of November., Have never had to wait for Tilapia to grow to a certain length or maturity to start feasting on FA .
