What type of power filter would be the best for my goldfish?

Question

ok i have four gold fish that im going to move to a thirty gallon and its probably the tank they will be for the rest of their lives. i want to get the best power filter for them. ive looking at the new tetra ones and aqueon ones. does anyone know which one would work the best?

Answer 1

get a canister filter

4 fancys need 50 gallons

4 commons/comets need 80 gallons

they grow over a foot

Answer 2

Ignore whoever said the Emperor 400, that filter is way too powerful for a 30 gallon tank.  

But the Emperor 280 Bio-wheel is what I use for my 30 gallon community tank.  It is an excellent filter, and would work great for you if you were to use it for your gold fish.

Answer 3

emporer 400, or ac 110

Answer 4

There is no best or better or perfect.  It is a matter of your personal preference and your tank.  As long as your filter will turn the volume of your tank a minimum of 10 times per hour any filter will work just fine.

Personally a regular whisper or tetra hang on filter will be good for your fish
