Can't you see the differences between goldfish and bettas? Warm water fish and cold water fish DO NOT MIX.
Mr Champagne, it might help to listen to the bits of information we give you- we might seem wrong now, but it'll help you in the long run!!
The members on here are very, very knowledgeable about bettas as well as their tankmates. We give good information and are not just telling you this stuff for the heck of it. But, do what you want... it isn't our fault if your goldfish decides to eat your betta or they get into a fight and get badly injured. I'd like to see pics as well.
