I took some of the longer mangrove out of the overflow and placed them in the tank since I noticed that they seem to do better completely submerged right after shipping. After reading what I did about mangroves, it makes perfect sense why this would be good for them. I stuck them all along the backside where I don't have many corals so that they would be out of the way of hitting any corals. I think I kind of like the look. The fish love to hide among them. Take a look and tell me what you think. Should I keep the mangroves along the backside or fill it in with coral?
