So in my 33 gallon tank i added xenias and a kenyan tree they have been there for a month now together the kenyan tree is all happy always opens up big and hearty and so do my other mushroom and star polyps and zoos as well. The problem is with the xenia's they seem to be skinny shriveled and closed up they have been like that since the addition into my tank but they have moved around the rock i placed them in and i have tried moving them around in the tank as well to see if its just water flow or lighting but still cant seem to make them happy. The water param are great they are just unhappy. Could it be chemical warfare even though they are not touching or even close to each other? Should i remove one or the other?
