So a week or so back the heat wave hit me hard and my tank water went up to about 89 for a day or so, after that I did water change and iced the sump and cooled the tank back down and along with the weather we got back to normal. Everything looks fine now except the zoas. They are still closed up, none have opened. Anything I can do besides being patient? Add special food targeted or move them closer to light or further away from light or anything??? Any help would be appreciated. Thanks!
