How is he doing so far?
He's doing extremely well. He's eating everything that I give him. He started to go for bigger pieces of food also. He adjusted to the lights in my tank and he's always out grazing. When I watch him, he's usually curious and comes to check me out. He only hides when something really spooks him or when the lights are out., but otherwise I always see him.
I hear they can be difficult to keep.
The Golden Angel is definitely not a beginner fish and probably shouldn't be kept by most average hobbyists either. I only have a month of experience with this fish right now, but it's doing much better than I expected and in such a short amount of time. I think the keys to keeping this fish are to pick a healthy specimen from the beginning and keeping the fish in a peaceful tank. While this angel is extremely shy, it should be moving around at least a bit. Don't take one home if it's just sitting in the back corner. Make sure it's alert of your presence. If it's out and goes into hiding when it sees you, that's fine. You also have to make sure that it can maintain its balance. If it can't, it's suffering from decompression issues. Leave that specimen where it is.
Odds are that the fish won't be eating at the lfs because it's known to take a while to get adjusted to prepared foods, but if it's alert, keeping its balance in the water column, and has no obvious signs of disease like ich or popeye, I say that this is one of those fish that you could take home with you. I was told that my angel wouldn't eat for at least 3 months. I fed the tank more often than I usually do so that I can go through all the different foods that I have faster. Within a week, he was eating! Now I went back to my usual feeding schedule and he's eating formula one, formula two, spirulina, mysis, krill, and pellets. He goes for the pellets the most.
