OMG I seriously cannot breathe looking @ these fish. My sister and her fiance decided to get a tank and fish right after me and my boyfriend got our own. They have 5 goldfish in such a small tank. My sister's fiance said hes getting a 50 gallon tank in a couple of weeks. But still, these poor fish, all I think about is how they have no where to swim, and the living environment is not spacious. Even though they are golfish, I still think they should have a filter if you have several of them. I took a picture of there tank.. It's bothering me so much.. I told them its not big enough for the fish, but they keep telling me they are getting a 50 gallon tank in a couple of weeks. But those poor fish have to wait that long.. Here is a picture.. i LOVE all animals, and this is animal cruelty to me.
