Key aspects about animal behavior and the Fish Tower:

1.Preferred Swimming Region – The position in the water column that the species commonly inhabits. Top-level and all-level swimmers are best.

2.Sheltering & Open Water Behavior – If you don’t add plants or decorations within the Tower you likely won’t see a “shy” fish swimming up the Fish Tower as often.

3.Add more fish – Especially for schooling fish, having a group makes the fish more outgoing leading to more Fish Tower usage.
