Tank Size Input, new tank Options

[johnism]

Ok I am limited on space and I am trying to decide on a tank size .
I am only wanting Ranchu with a bare bottom set up. Proubly only two fish ( could I have three in 30 gallons ).

I would love a 30 gallon tank ( 20.5 L * 21 W * 18 H ) cube
but I might get a standard 29 ( 30 L * 12 W * 18 H )
I have a fluval 404 to use ..is that to much over kill?


Thanks for the input ,
John

I am not familiar with cannisters (is fluval 404 cannister? ); but the rule of thumb is to get a filter that turns over the water 3 to 4 times per hour. So if your tank is x gallons of water, the filter shall have a turnover capacity of 3x to 4x gallons per hour.
