MRHELLO, Nilotica's (Niles) don't do very well at all for algae control. They have a narrower food preference, reproduce less often, become sexually mature FAR later than Blue or Mozambique, and still die at the higher water temp range of the Mozambique.
This lower and slower reproduction rate is why Niles are the preferred fish for food production. That is also why one should use great care if using a food fish producer's stock for algae control.
So will Niles eat anything else that is in the pond if not the algae? I may have to find another source for my Tilapia this year then. Maybe I have received some hybrids before. Not too sure they care for the algae but they reproduced well in my tank. That is what makes it bad when you do not know for sure what you purchased.
(except with a net).
