Before I started wanting one I started researching how to care for a discus fish. There is a lot of information out there on how to care for this cool fish, but if you are not careful you could get bad advice. In my opinion this website is the best when it comes to teaching you what you need to know in how to care for one of these cool fish.
So, if you are thinking about getting one you should definitely do it! Just do your homework first.
