Aquarium Advice Newbie
hi and thanks for reading! I have three golden severums in a 20 gallon short tank. When I first bought them they were active and curious. After having them a couple weeks I changed the water and it seems since then they turned shy and hide all the time. Their color has muted also but changes back to normal when feeding. Is there a reason for them to all of a sudden be so skiddish? I watched these three in the local pet store for months before buying and they always seemed happy in their 20 gallon tank with no plants. Now after a month in my tank with plants and rocks they don't seem happy. What should I do? Any advice would be much appreciated.
