Need some advice on my Yellowheaded Sleeper Goby

I know it's been a few weeks since I wrote this, but I'm still deeply concerned about my Goby. I found him on his side the other day in the morning. Unsure if he was sleeping or dead, I began to feed him. He ate and I was able to feed him enough so that he was swimming around the tank again but this really concerned me. I turned up the lighting on my tank to encourage more algae growth, and it's been working slightly on the sand.

So where I stand now I need some advice:


Along with the cultivating the pods I have in my farm tank, I want to purchase some bottled pods to encourage some rapid growth in my tank, and newly created fuge. I've always bought Tigger pods in the past. I also saw Arcti Pods. Would a Goby eat Arcti pods? Is it worth buying a bottle of them? And finally, if anyone buys their pods online, where do you shop? I've tried a few places, each seem to be fine, but everyone charges $20 shipping which sucks for 20 dollar bottles. Any other advice to save a fish would also be helpful.

Thank you!
