I am really mad at you people about buying a 5.5 gal tank with accessories. Your filter system in the box is for a 10 GALLON fish tank!!!!!!!!!!!!!!! When you hook up the filter system, to the tank, the current is so strong that fish get swirled around, and will only stay on the other side of the tank. You need to evaluate the product, before you allow it to be sold!!!!!!!!!!!! It doesn't take a idiot to see what happens when your turn on the pump on and see how the fish react to it! I had to go out and get a Tetra filter, that specifically says for 5 to 10 gal tanks!!! It is much smaller and the fish go all around the tank now !!!!!!!!!!!! I am bringing back the two other aquariums. I will never, and I will encourage others, to not buy any product labeled Top Fin, until this has been corrected!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
