so if im lucky enough to get the tilapia to have babies in my tank (150 gallons) what should i do to prepare for the little ones? should i build some kind of stucture in the tank for them to hide?
Ideally you would place the mother in a "birthing tank" if you want them "all" to survive. Take her back out once she stops taking them in her mouth after a few days. Or you could just build them a thing to hide in and hope for the best. I am sure some would survive... Honestly, in only 150, you probably don't want that many anyways.
