New to the forum, but just had to join after years on here reading others questions etc..I'll get straight to the point, as we all know thus hobby could be quite crazy, beautiful and sometimes just depressing.. today after coming home from work I noticed something a bit different.. the strain of zoa was pink hippo or chucky bride I think they the same bs. So we'll leave as that jaja, these names I tell ya! Anyhow it's a 2 polyp frag and been doing Great! But when I got home they had black spot like as if they were smudge or perhaps received too much light?? Any how I got a bit upset and figured I'd move em some place with shade and shortly I though nah and placed them back to their original spot.. they close up and shortly after they open again and everything was just back to normal as if nothing ever happened?? If it was smudge it would have taken perhaps 1-2 weeks.. but apparently it must have not.. just wondering has anything like this happened to any of yall?? After bout 6 yrs in this hobby I still get amazed and confused.. just something weird I wanted to share and see if other had anything weird like this happened! Cheers!
