Well they are not endangered in our dam.(now Nile tilapia)
Don't wary they will be going to our dam wen the new fish come.

This also concerns me.. you could be putting diseases into the wild that the native fish have no imunities to. It's illegal in many places to put fish into lakes.

just because something has a good presence in your area doesnt mean it exists in the rest of the world, and can very well effect it. anyways, a raw shrimp/alittle fish food or even a few pieces of live rock would have got your cycle on its way.

The fish are native to South Africa and I live in South Africa,we have this species in the dam.

This is how they look wen they are half a kg, they grow up to 4.6kg.
PS:the ones I have are smaller then 1''.

I live 350k from the pet shop that have the live rock and the fish. They can take allot more then any fish I know and I don't think you know much about them.

And the blue tilapia is world wide.

I would be more concerned as to why you are cycling a saltwater tank with a freshwater fish? Not only is this harmful to the fish, by using to cycle in the first place you are severely doing harm to it, and then you plan on putting it into the wild.

That is not the way to do it...sorry but I think that is just wrong. Unless you are running a canister or HOB which as people have mentioned are more harm than good on a saltwater tank then you ARE GOING to NEED live rock sooner rather than later otherwise your tank will be a mess..

Just my opinion.

I get you all, but this is a marine fish, and you can see them on the coats of Mozambique in the ocean.

Google. Oreochromis mossambicus

Mainly a Freshwater fish but "It also tolerates brackish water"- from wikipedia...

Brackish water is lower in salt content than what is required for a full saltwater tank. Why not set the tank up correctly first time otherwise you are going to messing around with the SG once you are ready to get saltwater fish.

Not to mention as well that fish is way too big for a 20g tank already...
