FA: filamentous algae aka pond scum.
Not an expert on tilapia but i think 3 to 4 lbs. with some bigger? However if your temps drop below 50 in the winter they won't make it which will obviously decrease their maximum size.
Good fish to eat? It depends. Just like some species some like 'em some don't. However they are widely produced in the aquaculture industry so the general comcensus is they are good to eat.
