i found a very fuzzy nudibranch, redish-brown and orange in color, also noticed my tank was at 72 this morning, i turned the heater up just a bit and have the nudibranch held hostage in a tupperware, i noticed no other nudi's but will be watching extra close for them, lucky for me most of my livestock are wrasse that pick at my rock constantly, hopefully they takeout any others i dont find
