One thing that gets over looked is nitrate which is the end product of the nitrogen cycle. You have a tank and filter running which converts the ammonia to nitrite and then to nitrate, but you don't do water changes or have plants to get rid of the nitrate. Nitrate builds up and makes the fish very unhappy so they are not in the mood to raise a family. If you have a male and female and the water quality is reasonably good and water temp 75 and up they will spawn.

We don't know what else to do to bring the water temperature higher. Because we had the system for over a year now and we don't have any babies ??? Help.

Thanks so much. Also Im looking for prawns around my area, Melbourne Fl.

@Bryan Acred- Floating a mop (the type made of yarn) in the tank will give provide protection.

All I have is the main 300g FT and the 190g. Do need to remove the female once she has released the fry?

I use bare bottom tanks with a few flower pots laying on their sides. I leave the females alone for as long as I can, until she is near ready to release them. Some times this isn't possible so I move her to an isolation tub, but she usually spits her eggs and or fry so I have to use an tumbler. Give her a couple days rest and return her to the breeding tank.

I have them breeding in a 55gal aquarium with no problems. Just need to make sure you have more females than males in the tank with nice places to hide. I have sections of 6 inch blue pvc tube cut to about 8 inches long for hiding places.

I also have a 29 gal aquarium that I use to take the female to when she is loaded with fry in her mouth. There they get released into that tank and then I just put her back into the 55 gal tank to start all over again.

I have a 190 gallon tank that I want to use as a breeder tank for now. Do you keep the Male and Female in the tank once she has released the fry?

thanks.

I want to try breeding tilapia in a 150 gallon aquarium. How should I set the aquarium up? What kind of filtration to prevent loss of eggs or fry? Gravel or no gravel and what kind?

Any other suggestions would be welcome.

Thanks

My tilapia spawned outside the last week of December so I got all I need for this year. I still had 34 big ones from last year in my 3000 gal pool but those two days of very cold weather last week caused 8 to die, I'm pretty sure the temp went into the 40's. Those who are having trouble getting them to spawn I think perhaps your trying to hard, just get a big tub or kiddy pool and toss a few in and wait till you see fry swimming around the edges. For aquarium spawning I use a 65 gal with two males and 5 females. I put two clay 6 inch saucers at opposite ends of the tank, this arrangement works for me. My own feeling is 'survival of the fittest'. I've left my tilapia outside for the past 3 winters and yes I loose some but most survive.

My tilapia never did breed in an aquarium for me.  When I threw about 12 of them into a duckweed tank (of about 300 gallons) and the water was up in the mid 80's we had lots of breeding going on.
