I agree with you, alot of people do agree with the same thing, but also some don't. Some people can't help what happened, for instance when I got my fish two years ago. I got it from a petstore and it was marked as a comet and looked exactly like a comet and was a baby, certainly a 30 gallon tank was big enough for 1 comet, but then now 2 years later I find out that the pet store was wrong, my fish is a koi/comet hybred and can get to 4 feet long, I just found that out not too long ago, and that made since as to why she just doesn't stop growing, now that I coiuldn't help, I had no idea and obviously the pet stores didn't know that it wasn't just a Comet. Now that I do know, i am going to get her a much bigger tank

Like my rabbit, I knew what breed she was and I got her the proper space and everything, she has more space than she even needs because I knew how big she'd grow, but I didn't know how my fish would get that big because it was listed as a comet.

But please, don't get me wrong, I very much agree with all of you, if you know what animal you want to get, you should get the proper tank size, cage size ect before purchasing the animal.
