HELP! after weeks of hardship, fish growing black on fins, burst bubble eye bubble?

to summarize this:
two fish left, one of them with extensive black on the edges of his
fins (but this looks like a part of his normal color, but 2 weeks ago
he was 100% orange) , one of them starting to get black blotches, and
(its a bubble eye) with a burst bubble.

is the turning black normal?

I have two goldfish. i started with five and far to little water (5
inches or so of fish and only 10 gallons, we were misinformed by a pet
store employee), and after about a month or so all but two fish have
died. One is a bubble fish and the other i cannot recall the name of. i
believe it is LIKE a lionhead. it does not have a dorsal fin, is
completely orange, and both seem happy finally.

this is what happened:

1. the fish started sitting on the bottom of the tank. they seemed
depressed, so i got the water tested, and ammonia, nitrates, nitrites
were normal... i bought some more plants for them and they started to
get better until one of them (the actual lionhead with the "growth" on
the head) got white spots... the others started to get SOME white
spots, but the lionhead really had them badly.
i changed 50% of the water and started to treat with rid ich and
unfortunately the lionhead died... the other fish had their ich clear
up.

2. a second fish (which was one of the more stressed out) died...

3. a third fish (a tiny little one) died.

4. the fish that remained stopped going to the bottom of the tank and
are now simming very happilly.

today though i was siphoning out some water to do a water change (a 25%
change) and install a bubble setup to make the tank livelier and the
bubble eye got too close to the siphon and his bubble burst.

i also noticed a week or so ago that the completely orange lion head
type fish started to grow black on the edges of his fins. the fins
appear completely normal and healthy, but there is black, as though the
fish is just growing larger and turning black...

the bubble eye is getting a few black spots, but it still looks very
happy, swimming all the time, eating, etc.

so any advice? what is with the black??? why are they changing colors?

thanks.

the black is a sign of ammonia bur. Did you cycle the tank before adding the
fish in???
Black is a sign of healing though

i know the problem why your fish died.....you had 5 fish in a 10
gallon...holly cow were you overstocked.....

yes, and as i said already, i admit i overstocked it. i was misinformed
and the problem has now fixed itself with only two small fish left.

yes, the water was cycled... and the test on the water was one on THREE
different test kits, so i dont know what to tell you.

but glad to hear they are healing, thats great news!

You're still overstocked, do 30% water changes ever 2 days and treat the new
water with a dechlorinator.

if you didn't cycle..there was NO way the ammonia nitrates and nitrites read
normal....sorry

Yup. Black edges to the fins is the sign of too much ammonia in the tank
water. Immediate remedy is do a large water change to get rid of the
ammonia.... 'til you cycle your filter properly.

I think that the OP might want to actually *check* the ammonia levels. My
NewFish has some black on his fins, and my ammonia is at 0. I think it's
just his coloring.

i did check them, with three different test kits three different times.

ammonia was good actually. i took it to an aquarium store to have them
check it since i dont want to risk fouling it up myself.

were the levels 0ppm?

My wife picked our 2nd orange fantail from the LFS tank because of the unique black lining on the edge of its tail.
At least, we thought it was unique.....
3 weeks in our tank and the black color is slowly disappearing (tail becoming fully orange).

Am I to understand that the LFS sold me an orange fantail that had suffered ammonia damage, and is recovering in my tank?

He/she is probably just developing mature coloring.  Many goldfish will be
widely varied in their coloring as juveniles, but as they grow up they will
become completely orange.  I bought 4 feeders of all different colors and
patterns.  Every one of them is solid orange now.

Would a 2mm-wide black lining along the entire edge of my orange fantail's caudal fin and a 1mm-wide black lining along it's dorsal
fin be able to disappear in just 3 weeks as a result of maturing?
I though these color changes take quite a bit of time to develop.

My 2nd fantail (Clinton) is completely orange now and looks just like my first fantail (Carter).

I did the same 'mistake' once and bought a couple of very cute and black
orange gold fish once and thought that they would stay that color. They
dont, they just look funny until they get their 'normal' orange color, but
when I started with the goldfish's I didn't know that...

That sounds like the fish has recovered from amonia burn in th past, you
sometimes see that if the edges of the fins has become damaged by finrot or
amonia burns, when the tissue grows back it starts out black and then turns
orange over a couple of weeks...

You named them :-)

I think Calico Fantails retain their mixed colorings into adulthood.

Wish I had known that a month ago. But things look good in my tank now.

Yeah, and my Red Cap Oranda is named Reagan :)
The Republican is not giving the Democrats a fair chance at the food at feeding time :)
But the Democrats have been known to gang up on the Republican.
