I can't add much - I agree wholly with Amey and Jeff - get it out of that moss and into some brighter light. Amey's right - those leaves are far too green. Deep green on low-light houseplants is desirable but orchids generally have far more yellow in the leaves when they're getting enough light. I have auxiliary lighting on my orchids - some are under fluorescent tube grow lights, but others are under "task" lights that have strong daylight fluorescent bulbs in them. The individual plant that's closest to the smaller growlight gets a good bit of light - I find it keeps the leaves their proper color - but I only use the auxiliary lighting in conjunction with somewhat bright indirect natural light, and I only grow my lower-light plants under them - like my paphiopedilums. Just my 2 cents worth - good luck with your phal!
