Hi. I have probably quite a far- fetched question here. I have many aquariums, each with its own ecosystem and I know alot about the types of habitats that I have. But I also have a couple of amphibious tanks, and am having compatibility trouble with one of them. Have a large tank with Chinese Fire Belly Toads. They are doing great, seeing as I have not yet disturbed their ecosystem with guesswork. But am close to experimenting if nobody can help me. I am looking for some type of fish of Chinese descent to accompany them in their tank. Not only is their water always cloudy, but something is just missing...Water with no fish???. Anyway closest thing I could come up with was chinese Sucker Fish, but they are NOT from China. What kinds of fish are from china that would suit my needs does anybody have any idea where i can find out?
