What to look for in unhealthy corals

[petroreef]

Hi R2R,

Im relatively new to SW and my tank has been chugging along for the past 9 months with relatively no issues (minus aiptasia). Was looking at my torch coral this morning and noticed its not as puffy as it has been in the past. I'm not really sure how to tell if its mad at me or not though. Are there any tell tale signs to look for with them. Picture below.

Excellent question but I think you have already answered your question - you noticed a difference in your torch by closely observing it for the last 9 months. Corals seem to be just like people - they have good and bad days and sometimes you just don't know why. Or it could be the start of something more serious. I have had luck with torches that didn't fully extend and started receding by putting in Dr. G's Reef Dip for 6 hours. Watch closely and good luck.
