I would like to explain that anything posted on this thread will be about mollies, monos, and green spotted puffers in our reefs. IN MY OPINION!, these three fish should live happily in a reef, but remember that all fish are different and not all fish are as strong as others. I will answer questions and I will only do so if I know the definite answer. If not give me a few minutes to do some research on official websites dedicated to the question you ask. I wish to inform that I do not care if you insert your input on this, that is fine I encourage that, but please be nice about it. Thanks and happy reefing
