Red Hook Silver Dollars

[CanadaPleco]

Wondering if anyone has any Red Hooks? I got a school of 6 of them over a year ago, and they have since gotten huge, approx 4-5". They must be several years old though as they are getting a LOT of red spots on them. They look awesome, I will have to post pics shortly as I rarely see pics of mature red hooks. Just wondering how many of you actually have nice mature red hooks? Or have seen them in this state?

I have about 5 or 6 in the 15k. You can see them in the video in the signature. They are probably 6" tl. The black bar red hooks are 12+". I also have a few more about same size as yours in a 180g
