Yes, and the 4 items can be used for any and all fish. Doesn't matter if it's from the LFS or the lake near town. If you are not prepared to keep those fish in a healthy state, then you shouldn't have them at all. I've researched all the fish that I keep, and am prepared for upgrades as necessary. It's like when I got my 26G, and 2 fire eels. People ragged on me for doing so without even asking what my future plans were. Well, when they got to about 5 inches, I went and bought a 55G for them. Now they are about 13 inches each, and still growing. And I'm hoping to save up enough for the ultimate 265G that I really want by the first of the year, specifically for the eels. I've done my research, and have some awsome tanks, and love what I'm going through with my Bolivians and GBR's. It's a great hobby. But if someone takes the hobby and expects minimal changes to fix their major problems, well, they shouldn't have started in the first place. That's just how I feel about it. And if you are pulling a fish out of the lake near your house, all I can say is if you've researched the fish, checked and found it is legal to have it, and have the proper setup, then you will have an awsome tank. But if it's illegal, and you don't have the proper filters, chiller, etc, then expect problems. Not only in the health of the tank, but legally. And the other thing, if you haven't adhered to the 4 items above, I guarantee you won't be happy with the problems that will arise. That's the fun of the fish hobby, doing research, learning all you can, keeping the fish and the tank in a healthy and awsome looking environment. What more can a person do and really appreciate what they do. AA is AWSOME.....
