Whoo Hoo. Update.
I've done a 2.5g water change for now, the fish just kept to the back and seemed fine during it. I made sure I didn't spook the fish too much either. (I'll do another 2.5g water change tomorrow morning) About 10 minutes ago I fed the tank a mix of Spirulina (sp?) And another brand of flakes , I think it's called new life spectrum. I also put a little mysis into the mix, as well as some garlic extract. The fish was cautious at first, but in no time came and pigged out big time! I was very pleased... I haven't seen it twitch for quite a while now either.
