hmmmm do a big water change? maybe there's something in the water its not liking? if its mouth is huge like that it means stress so it might be the water. idk about the MH bulbs because i have no knowledge or experience with them. i thinking its the water condition because ive had bubble tips under my compact florescent lights and do fine under them. good luck bro i know how it feels to lose nems :(

Big water change, 25% today, wait two days, another 25%, run carbon, check your alkalinity, and if you get new bulbs (you should) you need to reduce your photoperiod to 4 hours and increase by 30 minutes a day until back to normal.
