http://alliedaqua.com/blue-tilapia-fingerlings.html The thought buzzed my bean to get some to mess with. How many would one put in a small 40G tank for starters? (have 4) Also have (2) 100G and (2) 180G if needed for growth.
Lots of variables there. Others are a lot more knowledgeable about carrying capacities than me. I would say if you kept it to the 40G, about 25. Keep there growth monitored so they don't get to big by spring time for release. Possibly in the 4-5" range? If you wanted to make use of all those tanks.... get hundreds!!!!
