NICE!!! That's a lovely coral!
If he starts swimming vertically with tail down that would probably mean a spinal injury.my other half fed my fish today and large male pintail leaped out the tank through the feed hole lol.... she said she scooped him up immedately and put him back in tank. she said he seems ok just scared..... i told her to watch his swimming and make surehe eats... anything i should look for. spine damage or anything?
