Hi NZed,
Your tank is way too small for the ammount of fish you're housing in
it....it would be very wise to get a bigger tank ASAP....remember that
goldfish are very dirty fish and need around 30L of water per fish because
of the ammount of waster they produce! You can even stunt their growth if
they are kept in crowded condidtions!!
...You are right about there not being enough oxygen in the water...fish tend
to gasp for air when the water isnt oxygenated properly....what are your
water parameters like PH, ammonia, nitrates, and nitrites? If you dont have
these test kits, it would be wise to purchase them as they are very
valuable!!

While you are waiting to get the new tank, increase the airation of that
tank....it might be wise to move some fish into another tank with
aristones....

BTW.....Are you using a water conditioner to remove clorine and chloramine?

Hi
I am new to the newsgroup and have recently purchased a tank.
I have had very little experience with aquariums apart from keeping a
couple
of goldfish in a bowl as a child.

We recently purchased a 29lite tank with a build in water filter...carbon
and wool.

When we bought it the lady in the shop said that it could hold the
anticipated 8 goldfish we wanted to purchase.
8 red comets approx 4 to 5cm long.
They have been managing for a month ok. ...so I added a couple of small
blackmores.
A week later I have noticed that they fish look as if they a gulping all
the
time. Not enough oxygen in the water ?
I have three oxy weed plants.

I just noticed today also that the comets have red around the gills....not
enough oxygen in the water ?

I also noticed that two of the fish ....dorsel fins are sometimes flat.

Today I did a water change...since a week ago.
I also purchased an airstone.

My questions

1 How many goldfish should I have max for a 29 litre tank ?
2 Now that I have 10 fish ...I am considering getting a bigger tank.
What
size tank do you recomend.
3 I have seen a very nice Juwel vision 180 litre tank, which looks very
nice. inbuild filter.
Would it be big enough for the 10 fish and has anyone had any experiences
with the Juwel tanks ie filter systems

Looking forward to your replies.

Regards
NZed
