<p>I started with about 20 tilapias about 3 weeks ago. They were smaller than 5 cm. And now they are about 10 cm long. They eat a lot!! I feed them about 5 + times a day. But now I'm feeding them less a day. </p>

<p>Just a few days ago Jon Parr said 75F was about where tilapia will start to breed, so yesterday I started to let my tanks warm up a little. I had been keeping them at 75F and today I just measured 81F, and to my surprise those little fingerlings that where hatched in early May began to show their red breeding colors and behavior.</p>
<p>I've been saying 2" but I guess they are actually closer to 3". Even so it's been less than three months. </p>

<p>But I plan to keep these 2" fingerlings in the aquarium until they breed. That should be somewhere around September, and I'll be sure to take lots of pictures.</p>

<p>@Bob Vento - Since it was you who first asked about breeding tilapia I hope you got your answer. I seem to have hijacked your discussion.</p>

Bob C, where did you get the tilapia? They look to me like California Salton Sea tilapia, which is about 80% mossambicus and 20% hornorum. The dorsal spot is common, an fades as the fish ages. Saltons have horizontal bands, blues and Niles have finer vertical stripes

<p>Fish identification is really difficult because as fish mature or change moods their colors and shape change. For example I don't see the dorsal fin spot on my 8" fish, and as I recall they have shown bands on their bodies, but currently I don't see bands on either the 2" fish or the 8" fish. Maybe they have to be happy or sad to have bands. Seriously they do change appearance according to mood.</p>
<p>As my fish matured their lips became more pronounced as shown here.</p>

<p>My 2" fish have lips like this.</p>

<p>If you look at the pictures at MonsterishKeepers you will notice some of his fish have two lobes on the dorsal fin. That would indicate to me that he has two different fish, but he indicates in the text that his fish are all Oreochromines. I don't think that other fish is even a tilapia.</p>

<p>Hi Bob. Thanks for the careful analysis. It is greatly appreciated. May I provide an alternative one? Based on the photo above your fish may have some mossambicus in them, but their phenotype is primarily blue (Oreochromis aureus) though they are likely mixed with nile as well (O. niloticus). The dorsal fin spot is shared by many species in this clade of fish as is the red belly in mating colors. But it is the iridescent blue head and color around the mouth and indistinct striping on the tail that are the characteristic of the blue tilapia. In the U.S. most blues are mixed with niles as a matter of practice to produce a superior fish. Also, the body shape particularly around the mouth is very indicative of the blue & nile tilapias as well. Here is a better picture of a hybrid adult:</p>

<p>We recently got a wonderful fish from Sheri that is a mix of all three as well.</p>
