Hi...was just curious cuz I saw two different corycats today...green corydoras (which I bought) and Emerald green corydoras (which I never heard of before)...so whats the difference? Really curious (but too lazy/busy to do a search rite now)...hope someone can help! The emerald green ones looked a bit bigger...so is it a size difference or were they just older? (The green ones are babies still)...hmmmm....
