Do you have any recommendations on what I can do to make the back of the thermometer not so shiny? Fighty was flaring at his reflection in the reflection of the thermometer off of the glass (not the actual thermometer, but maybe that could happen too.) I was thinking about duct tape at first, but I don't know what the glue would do to his water, so I didn't do that. I don't want to color it with any paint or markers, cause I don't want that in his water either. Maybe scuff it up with sandpaper? But, then he might catch his tail/fins on it. Maybe I should look for another thermometer... What do you guys use? Any suggestions would be appreciated!
