I'm a newbie to aquariums and started with a 20-gallon freshwater with a beautiful
Red Ryukin goldfish (named Angelina Jolie!), some sunburst platys, some yellow lyretails, and a few neon tetras. My tank's been going strong for almost 2 months and I got brave. I thought I'd take a shot at getting a cute green spotted puffer and have had her for 2 days and all has been well.... until I got home today. I'm totally devestated to find that my
GSP has nipped the beautiful tail fins on my poor Angelina and has even taken a chunk out of my lyretail. Oh, and I'm missing a neon tetra.

So, I took back the GSP to my LFS. I feel like a moron because I didn't believe she would really nip my fish's fins-- she looked too cute an innocent. Boy, was I wrong.
My question is--- is there any way to fix/repair/heal my Angelina's tail fins and get them to grow back?? Every time I look at her I feel horrible for my ignorant mistake in getting that stupid GSP. Help!!!!!!~
Thanks
