Please help. Everything was going so good. We made it through the cycling and we've been cruising for a couple months. This morning my little boy woke up to a sick apisto. It's his favorite fish. The color is almost gone. There are some patches on one side of the body. He is acting lethargic. Just barely moving and tucked up between the filter and the glass. It's hard to get decent pics, but I tried. Hopefully someone can save him. Does this ever end well?
