Recommendations For A 120L Tank Please

[shakespeare]

I've just been given a 120 litre tank (interpet with P4 filter)by my neighbour - very generous man! Anyway, I've never had an internal filter before and just wondering if this P4 one is suitable. I shall probably put my 2 lionheads into this tank so need an excellent filter. Is the P4 fine? Any suggestions please.

The goldfish will need a larger tank in the long term, but the 120 with any filter rated for 120 litre tank should be fine in the short term for two goldfish.
