So i recently got a new torch and today i woke up and it looked crazy. One if the tentacles very specifically looked brown and discolored. I dont know if one of the fish did it. I know my damsel likes to nip at things sometimes as she swims around the tank ive even seen her donit to a coral or two never the torch though. I haven't seen brown slime or anything like that coming out of it so i dont know if im dealing wit that brown slime disease but as you will see in the attached picture it doesn't look happy. The torch i had previously seems to still be doin alright so far but idk if its me being nervous or what but the other torch looks funny in some ways to me the tentacles seem fat but small at some tips idk the more i stare at it, it seems fine but i also feel like the more i stare at the one with the issue the more im looking for things wrong with the other one. I even feel like the other ones tentacles look like they have a tint of purple in some areas. In the provided picture theres one small tenactle next to the other torch thats nit doing great thats looks small and darker compared to the rest. Im hoping my older one is also not being effected. I even have a hammer in this tank that seems to be doing alright so far too. Ill keep an eye in the other torch and the other corals over the next few days but i was just hoping you guys could give me some opinions based on what you see here. My parameters are all where they should be as far as i know. This torch seems to be the only issue at the moment. I did move them around the tank 2 days ago for what i thought was a better spot for them could that have caused this? I also lowed the temps by literally 2-3 degrees because the water temps were reading sat 85-86 and i thought that mighta been a bit too much. Any ideas?
