I just got a batch of these from a friend and I am comparing them to niles. So far the growth rate seems to be about the same.

These are a cross between Blues and Niles but bred with a white color morph. They breed true, even though they are a hybrid. They supposedly have the same cold resistance as Blues.

If anyone has raised these, let me know if there is a big size difference between the males & females. There isn't with Mossambica and Horonorum, but it is huge with Niles with the males getting to be 3-4 times larger than the females.
