hello everyone. i am very new to reef2reef so bare with me.. i have a 4" by 2" bubble coral that was given to me about a month ago by my friend. before i got it it was not being taken care of and was in a ten gallon with stagnant, unfiltered water for weeks. since i put it in it has had great polyp and tentacle extension and hasnt fluctuated; if not, gotten bigger, BUT...... since ive put it in it has been getting brown spots in its polyps. it almost looks like brown algae is IN its bubbles... i think its BJD but i dont see any tissue recession or retraction at all. IM PUZZLED HELPP!!!!
