I understand this topic has been posted multiple times in the past and I have read all of them.. but I want to get some more updated information or share any new experience based on emerald crabs…. My tank is now 5 months old, pass ugly/Dino face… so maturing phase I guess… I started seeing bubble algae’s here and there.. starting to spread more and more.. I have been manually removing them. I am trying to be more proactive here… I am trying to avoid adding chemicals, I think that’s the best route and keeping my tank more stable that way… majority of hobbyist suggesting adding emerald crabs, however, there’s been report about them eating corals… I have mixed tank so I have all kinds corals and any thoughts? Please share your experiences or solutions.. thanks
