I am raising Tilapia fish in my aquaponic set up in my greenhouse. I bought a 100 fish that were about 1/2 inch long January 1st and now they are about 10 inches long and weigh over a pound each. I took 5 female fish a male and put them in a 55 gallon glass aquarium as a brood colony hoping that I would have a bunch of new baby fish. But the fish have not been cooperating, no baby fish. They lay the eggs and then when the male fertilizes them the female momma fish picks the eggs back up and keeps them in her mouth until they hatch. As you watch the fish the moma fish that has eggs in her mouth becomes evident because her cheeks begin to pooch out and she doesn’t eat. I went out to feed my fish tonight after church and hallelujah, and one of my fish is pregnant. They usually have about 200 babies. I have a 10 gallon glass aquarium set up and tomorrow I will net the Momma fish and put her in the 10 gallon tank by herself and when the babies hatch she will spit them out, and then I will net her and put her back into the big tank before she eats her babies, where she will stay until she gets big cheeks again. The babies will be just 1/16 of an inch when born and when they grow to be about 1 inch I will put them in a big 300 gallon tank until they get big enough to eat. It won’t be long now before I will have lots of fish. Cool.
