So I now know the most adorable fish are Freshwater Dwarf Puffers! No doubt about it. I had some ordered from my LFS, and they finally came in, so I picked them up yesterday. They aren't even an inch long! I put them in a 20 gal with 4 hide decorations and some plastic plants. I was worried that they would get very territorial and fight, but as soon as I let them out of the bag, they each went to their own spots and have been chilling there. I rarely ever see all 5 at once, lol. Of course, the tank that they are in is only temporary. They will soon go in a dirted planted tank with a sand/rock substrate. So, anyways, I added a couple of pics of their tank. I know the rocks are a bit too big, but they were all I had on hand at the time. What do you think?
