Clownfish is Always Hiding and is Inactive

Hi.
I'm new to the site and relatively new to the hobby. I just took on the responsibility of caring for my families 14 gallon Oceanic Biocube. So far everything has been going great, but there is one problem that I have had a very hard time trying to fix. The tank is about 7 years old and used to have quite a bit of livestock in it (looking back me and my dad definitely overstocked it). At first we had a true percula clownfish, a purple firefish, and a six-line wrasse. Everything was doing okay for a while until I convinced my dad to put an archeye hawkfish and a bubble-tip anemone in the tank (I was still a little kid, in my defense). To make a long story short, within a month the anemone split in half and died, the wrasse and dart fish followed shortly after, then, finally, we had a massive outbreak of Cyanobacteria that pretty much engulfed the entire tank (almost all of our corals and inverts died out shortly after). Eventually my dad started to really fall back on his matainence for the tank and the problems just continued. The hawkfish survived for a little over a year before it dissappeared and the percula has been on its own ever since. Fast forward to today and I have got the tank back on track and the cyano under control. Everything's going great and I even have two corals making a miraculous comeback. So here's my problem. The clownfish never leaves the rocks, not even to eat. I know something has to be wrong because up until about a year ago he would swim around the tank and would always rush to the surface during feeding time. Now he just pokes his head out of the rocks all day and only eats food that flies right in front of him. This has my worried because it makes him difficult to feed and leaves a lot of uneaten food around the tank. He hasn't grown in size (he's been roughly 2.5 inches for the past 4 years) and if anything his environment has drastically improved. The water parameters are fine (with the exception of temperature which has always fluctuated from 73 f during the day to 69 f at night. I'm saving up for a heater to fix this) and the tank has received weekly 10% water changes for the last month and a half. No new live stock has been added so far, except for a small cleaning crew of crabs and snails, which hasn't seemed to affect the clownfish at all. We also relocated the tank from our upstairs living room to our downstairs living room a few months ago. This is about when the clownfish stopped being active, so I'm suspicious that might have had something to do with it. Again I'm sorry for excessive amount of information but I really don't know if any of it may be related to the problem. If anyone knows why my fish is doing this and/or how to fix it I would be greatly appreciative. I will try to answer any questions and provide any additional information. Thank you :)
 
With mine, everything changed when I put another clown fish in with them. My clown went from being a recluse to out front and center within minutes of the new addition. I guess mine was just lonely.
