Excellent job, the poster is starting to look really nice
Although the pic you had before as labrina, you've put now as biocellata. Crenicichla biocellata is a synonym of C. lacustris and you already have a pic for lacustris (the pic is a male, and the pic for biocellata is the female ) so you don't need the biocellata pic.
Also the first pic in the last row you've also put as lacustris and I think that's a jagui or some other froghead pike.
Other then that I don't see any other issues, except maybe walacii is a bit different then what i'm used to seeing, but I'll let other members here more knowledgeable then me check it out.
Yes the second is a jagui, don't worry about it, everything can be fixed. I'll try to find you pix of a tigrina and sp "cobra". I sent u a link for C.ypo u didn't put it on the poster, was it a bad pic?
