This is a display of all fishes that are available. 2x5 of these, to the right, must be separately bought in two available additional packs.
The Mollies are unique in that they allow full skin pattern randomization. That, in combination with altering their sizes, gives each fish a completely individual look then.
The tool that is needed to download to alter fish sizes in tanks, is available from forum posts.
The forum alos offers two or three collections of Highres background images that can be used for 2D backgrounds. However, you can use just any photo you like, but it should be Highres for sure, and not showing grains. Use Google Picture search for "landscape aquarium", and equivalent search terms.
