Hi and thanks for the comments.
When they arrived he hadn't the hump, and there wasn't any difference between them, they changed a lot in a week. They are really nice! I have 7 and there's another pair starting to mate
The Vieja zonatus, where 3, and I just had one male (sold a month ago), was really big and with very nice colors.
About the istlanum red, I just have a mean female, killed the others but she breed once. Same with turquoise, killed each other, they are mean.
The Herichthys Labridens "Blue Taniul" don't known, they were for other people, but I think there is atleast one couple.
Thank you for the coments. The breidohri have around 6''.
The thing I noticed more in one year is the width and robustness of the fish, aswell has the color.
