Do my fish need objects in their tank?
People usually add objects and ornaments to their tank to make it look attractive. Objects are also important for your fish, though, to increase their sense of security and to keep them active.
You should provide them with shelters that they can use as hiding places and to get away from other fish when they want to. Other objects should be provided for them to explore and swim around.
Don’t clutter the tank with objects because there still needs to be plenty of space to be able to swim around and exercise.
