Just purchased the Aquarium 2020 software and noticed the icon is horribly scaled on my desktop due to being drawn at a very low resolution. I took some time this morning to make a new one at the 256x256 max icon size, which will scale down instead of up if you use say 48x48 view size. Much cleaner look. Here's the link:

Just toss it in the same directory as the exe, then right-click on your desktop shortcut and change the icon to that one. Enjoy!
