Around 2 weeks ago now I ventured into fish keeping again, last time
was over 5 years ago. I am starting with a small tank, and maybe move
up in size. The tank is around 13-15 litres.


Well, there are several issues to address here. One, the tank is way too
small for those goldies. I woud hesitate to put *one* in a 3 gallon
tank.Goldfish are little poop machines, and filth up a tank quickly. Also,
they grow fast, and will quickly outgrow that tank, or they may die before
that. The algae bloom is quite common in a new tank, do water changes on a
regular basis to keep the ammonia and nitrite down until the bacteria in
your filter have a chance to catch up. BTW, have you tested for ammonia and
nitrite? These two substances are very poisonous to the fish, and should be
your chief concern right now.
May I direct you to a great resource, the "krib" FAQ.---

Goldfish (at least the Australian variety) seem to be pretty hardy. how many
people do you know that have a goldfish with no filter, and rarely do water
changes? I know of a few, it's common, so I wouldn't freak out, but don't
let the ammonia get above what it is now, do plenty of 1/4 water changes,
even one a day, until your filter catches up, this could easily take upto
six weeks.
