Bloody Streaks in fins

[Neil Cummins]

Hi

We have 2 Goldfish, one about 9 inches long, one about 7 inches. We have
had them for around 7 years and they are currently in a 150 litre tank with
an external ehiem filter (normally with a nitrasafe sachet to remove
nitrate) and water temperature kept around 22 degrees C. We normally do a
20% water change around every week which keeps the nitrate level below
50mg/l. The smaller of the fish has developed bloody streaks in its fins,
which are clamped to the body. The other fish seems OK. Both are still
active and feeding (usually dried food, occasionally frozen daphnia etc).

I have conducted extra water changes and treated them with Interpet Anti
Internal Bacteria (No. 9) (having removed the nitrasafe) but there has been
no change. I have not yet checked nitrite levels - I had assumed that if
nitrates were OK then the rest should be too.

Any suggestions welcome.

I had that problem once with a beatiful red carp I had about 10 years ago.
It has two reasons you should check on both:

1. Check PH, when exposed to an acidic water for a prolonged period of time
the fish will develop bloody streaks, its called acidosis.
2. It may also be a bacterial infection WHEN it is not accompanied with
extremely rapid breathing and wild dashing about the aquarium.

If number 1 is the problem you should correct the PH, sodium bicarbonate for
the water (to raise the PH GRADUALLY) and new carbon for the filter.
If number 2 is the problem there are several treatments out there like
Furan -2 , TC capsules, EM tablets or Nala Gram at your local pet store.
You should take the injured fish out of the aquarium and treat it in a
hospital type aquarium without carbon.

I hope this helps.

Carlos is correct, it could be acidic water but this is usually brought on by rotting
organic material in gravel OR sudden changes in city water ....

red streaking in fins is almost always toxic water conditions. once you have
eliminated the usual with test kits (how old are the test kits?) then just forget the
kits and do HUGE water changes for 5 days in a row. sometimes small water changes
results in "salt creep" where minerals build up due to evaporation of water.

another reason for red streaking is too high salt.

a third reason for red streaking on body (usually seen in koi) is ich.

I know the LFS is always talking about bacterial septicemia, but I frankly think it
is a very very rare condition and just a reason to sell people antibiotics to dump in
the water. remember that septicemia means bacterial infection of the blood stream
and is not going to be touched by typical LFS antibiotics in the water.

if there isnt salt in the water, after doing some big water changes add 1 teaspoon
salt per 5 gallons, no additives, dissolve first, add slowly. Ingrid
