About a week ago I bought a serpent star and he was fairly visible coming out in the mornings for a snack. Two days ago we had abnormally cold weather for our area and the heater in the house just couldn’t keep up in the middle of the night bringing the tank temp down lower than normal. Since then we had the heater fixed and tinkered with the tank heater and all the other inverts (FOWLR but no fish yet) are back to normal. I haven’t seen my serpent star though and I’m starting to get concerned. Is it worth tearing apart the tank to put my eyes on him or should I just leave it be?
