the grows to the size of the tank is one of my major parts of the presentation. I will definetly be talking about tank busters and the correct way to raise these fish, not the way many people do. Though I doubt that many people will be able to afford the size tanks that the fish need, like the red tailed cat fish, really needs a couple thousand gallon tank, which may even be to small then, and people put them in 125 gallons. I personally dont believe in keeping fish like that, but if you must, a 50000 gallon aquarium should be used so that the fish will think it is in a lake. I did read an artical about some one who did keep his red tailed cat that way.
Also, if I cant trade the fish back to the store, or borrow it, where would be the best place to put it? I know that I can give it to my local garden center as they do have a pond, but I think it is pretty good sticked already. And my coldwater tank is stocked full already.
