My GSP is in a 65gal acrylic tank in my office. He’s a super curious little guy but would have violent panic/freak out episodes at his own reflection and the reflection of movenent outside the tank (especially when people talk with their hands). Definitely varied depending on sunlight and time of day, but no combination of decor or shading variation seemed to solve the problem. It became a chronic stressor where some times he would spend hours hiding behind the locline returns and suddenly flip out at his reflection in the gloss black acrylic of the overflow box.
After reading about total internal reflection, I ordered textured opaque acrylic sheets to be used as a back/side wall insert in an attempt to break up the light refraction. It has worked wonderfully and my little nugget is much happier for it; as am I with such a huge difference in his behavior. Hope this helps if anyone else has a spastic puffer!
