Ok, so I hit a couple tropical fish - aquarium stores today. Both pretty high end with impressive coral and saltwater displays. I was a little disappointed in the lack of S. American - Central American fish and cichlids. One store had some monster arrowannas, cats and snakeheads but not many plecos at all. I'm thinking the main aquarium in town would likely be a disappointment as well so I'll probably skip it.
Here's a few pics, I'll post more and a few videos when I get back in town.
