Re: Hey I'm new. Quick few questions

Hello,
It looks as though the filter is positioned quite low in the tank. Normally, the nozzle where the water comes out is positioned at the water level or even above it to produce a waterfall effect, depending on the make of filter. Yours looks like it might be one of the ones where the water should be coming out and skimming the water surface, so that there's more surface agitation and water movement.
Just so that you're aware, a 12-litre tank is incredibly small for a goldfish - s/he won't survive for long in that and will need to upsize very soon. If you bought the tank today from a shop, they ought to be able to change it and sell you one that's fit for purpose. You'll see from
http://www.fishkeeping.co.uk/articles ... -size-life-expectancy.htm about how goldfish grow and how they need bigger tanks to prevent stunting and illness (and premature death).
In terms of general fishkeeping, the following articles should help too:
