What part of Ecuador are you in? Im in the US but have family that lives in Atuntaqui. On one of my last visits I was excited to see what was listed as a 'fish store' in nearby Ibarra. Well on getting there it turned out to be a hard core hobbyist who wanted to start a tank building business. He had some awesome looking oscars, green terrors and even some African cichlids but you would have thought some nicer stuff would have been available to him. He did have some young oscar fry that looked very interesting, likely from a wild caught source based off their pattern. Visiting a small pet store in Quito was very disappointing to say the least. Very common little fish with nothing of any interest. My dentist in Ibarra has a tank in his waiting room. He has angel fish and some neon tetra and thats about it. I had hoped that my Visit to South America would lead to seeing different fish but just the same old stuff you see offered to typical fish keepers.
