This site is all about rearing tropical fish. If you are into rearing and breeding fish, you might want to take a look at this site. It has numerous useful information on taking care of your tropical fish. Yes, they know that taking care of tropical fish isn't easy, especially if you are living in non-tropical areas, but don't worry the site has many useful tips for you to move along. We are not talking about some Tom, Dick and Harry site but a real expert behind the scenes. Surely their decades of experience will be useful to you if you are going to rear some tropical fish right? If not, the learning time and curve would be rather long and expensive. Just look at my experiences, they have been rather bad and killing fish kind of suck and it is cruel. You can also join their dicussion forum to read what others are doing with their fish as well. It is always good to share knowledge and experiences with each other, this way we could all learn from each other.
