Yeah most of it it actually beneath these smooth stones I've bought that are on top. This is an older photo and I've moved the stones around a bit so that not so many of those are able to be touched. :)
I probably should've just gotten a normal 5gal tank, but it could hold 4 gallons, and is perfect for a dorm room. There is a limit in the dorms that you can only have a 10gal tank. But I wouldn't have room for it anyway. I barely made room for this one, and I couldn't bear to put him in a bowl or a little tank.
I kept mine in the 4 gal version too. I must say, I couldn't believe the difference in his behaviour and 'active-ness' when I upgraded him to his 7.4. Tbf it doesn't take up much more space either with the biorb being spherical and his new tank being rectangular.
New two week old 10G tank for a few female bettas. Currently added 2 female bettas a week ago. We would like to see if we can get 4-6 females together. Please feel free to suggest ideas or suggestions.
