[raquel]

Mine were histrio's. My first tank was a 90 gallon with a 2-3 inch sand bed. It was 2 years old. I recently switched to a 38 gallon with a 2-3 inch sand bed, same old live rock, corals and fish. But the new (2nd) green clown goby also died.

Everyone else is fine.

Thanks for the info and the articles.
