Nice photos Tongue33. Herichthys deppii is a species not too many people are keeping.
Herichthys deppii and Herichthys sp "turquoise" are very similar. The main difference being the amount of red near the mouth. Herichthys deppii has alot of red facial markings near the mouth whereas the red facial markings on "turquoise" are near the top of the head.
Hear is a photo of an old sp "turquoise" I used to keep to compare.
