I've been looking through the native Aquaria maps with the editor since now we are able to do so, and I've noticed, all the fish that I have not been able to add in the editor seem to have no name ID. These fish include all the tropical fish, and the mino fish swimming in the background. So this leaves me with a couple of questions.
#1: How come these fish are not selectable in the entitygroups.txt, even if I add them by their picture names.
#2: How can we add these fish to our own mods?
#3: How do you put entities in the background layers... like the small minow fishes swimming around in groups.
