Lol Bev, you are right. I have nothing against these. I am just stating this may not be as easy and cute as it looks.
Even myself own such a thing. Well, it's more like a bowl, with water, shells, and a nice water plant inside, and some water snails (do they have a different name???).
I have it, cause I thought a Beta fish could live in it. Well, it died after about 2 weeks.
Good for you Lynn... so, I guess I am partly wrong
