Here's shot of a young one, they can look quite different from each other (color patterns, markings) depending on catch location of ancestors , or if wild caught, and range Costa Rica thru Panama.
They are insect and plant seed eaters in nature, so especially as they age, don't think of them as strictly carnivores, and feed a high protein diet.
There is a tendency for many to bloat, and I believe this is from the stress of high nitrates, and too much protein compared to roughage type plant material.
I was using a high Spirulina pellet like Algaemax, with every other day water changes, and had no problems.
