3 weeks ago my rose tip retreated back in the crack he lives in. He's got good color but barely pokes out during the day or night. Tank water specs are perfect. Using Hanna testers. Everything else is doing great. Was feeding him few times a week, he is hosted by a clown who misses him very much. My phosphates did rise a month ago but quickly corrected that. I did upgrade to the new 300 watt. 48" razor maxspect led light. Great light by the way. But I carefully started low and increased it over time to its preset lps setting. No idea what's going on. I don't think he's sick. His color looks really good. Any ideas.
