its a Blue dragon sea slug or glaucus Atlanticus they are found in Australia near the equator you should check them out they are so unique! almost like a cute little alien
They all actually seem to be getting along great! I'm just keeping an eye on them and getting used to their eating habits. The bloated one seems to be getting a lot better.
Thanks for that tip. When I bought my 10 gal tank today it came with a little thing of it to treat 10 gallons. But I also picked up a bottle from the store.
