Yea I hope they pull through. They are so cute and sweet. Even if they hide all day, they're still adorable. My sister used to have some in a 20 gallon and they would swim around a lot more with covered areas. She of course had fake plants all over the tank and some of those little bridges. Yes, she's one of "those" kind of fish keepers. But she had them for about 2 years. So I'm guessing they're hardy fish lol.
