I have a 30 gallon freshwater tank located in a corner of the house not far from a window. Its been there for many years. It has lots of driftwood, plastic plants, and other "hiding" places for the fish. I have three bottom feeders and 2 tetra types of schooling fish. All up around 10 small fish. I don't overfeed, do regular water changes, etc and from all appearances, the fish seem healthy. But they seem absolutely terrified. Most of the time they lurk behind the darkest corner of the tank and seldom come out, even when food is put out two or three times a week. I know that as a general rule, dark is better than light, but at the moment, my location choices are pretty limited.
So....is this a question of the fish afraid of other fish, too much decor in the tank, or this their 2 footed fish master's presence an issue?
Suggestions ?
