I got 4 Midas/Rd fish from a new fish friend of mine, and I noticed that about 3 days into me having the fish one of them has grown a very noticeable and prominent kok.

What's the typical growth of a Kok?

Also, how do you sex these things?

I think the one with the kok growth is a male, and is more true to one species than a mixture. He's been chasing 2 of them around in the tank, but there is one he will not bother with... So, I am thinking 2 males and 2 females?

Here are some pics.. The first pic is when I got him, and the last pic is him now..

Also, are they supposed to have blood red eyes?
