i think you are doing great considering, what you should have done with
those second lot of fish is say "no thanks"
and waited for at least a month before adding new fish.

I would try and take back the gouramis, and the shark for def, as these will
cause you problems long term, and will out grow your tank, they may also
intimidate the other smaller fish and cause you more problems.

Keep up the water changes, add some nutrafin cycle, keep feeding down to
minimum fish dont hurt if not fed for a day or two, also with no live plants
you are gonna have big algae problems so you to plants heavily and quick.

Hope that helps, di

My girlfriend bought me a 100 litre tank for my birthday a few weeks ago.
I
filled it with gravel a few fake plants and water and left the filter and
heater running for a few days.

I then went to my local fish shop and bought some small fish recommended
by
them to cycle the tank.

All OK so far right.

Then.... My mother boyfriend turns up at my house after 2 days of the
fish
being in the tank with a bag with about another 15 fish in it. They are
gourami's, 2 or three different kinds of mollies, a few red eyed tetra's
(i
think thats what they are called), some tiger barbs, some sharks someting
or
others (cant remember and i doubt they are real sharks).

So now i am doing a 20% water change every 2 days in an attempt to keep
the
ammonia and nitrite levels down. Yesterday ammoina was somewhere between
1
and 1.5 ppm so i did a 40% water change.

Nitrite is about 1.0 ppm at the moment. they have all been in there 2
weeks
now and *seem* OK so far.

Is there anything else i should be doing?

Thanks Guys

Chris

p.s. I'm sure i'm going to enjoy this once i dont have to do water changes
every 2 days!!
