Cardinal Tetras

[unclejoes96]

Two questions if I may please, I am very new to this.

1. One of the tetras has its fins all nipped (or rot I suppose) the other 3 are fine. Could this be as a result of a male Cherry Barb who does like chasing all around especially his female companion, but she is ok. Or could it be something else.

What should I do to remedy this ?

2. Another Tetra has lost a lot of its red colour, what could this be due to ?

All the fish are eating. The tank is 16 gallons, which cycled 2 weeks ago.

Inhabitants 4 Cardinal Tetras, 2 male Guppies and 2 Cherry Barbs

Cherry barbs are fin nippers, you didn't use the tetra's to cycle the tank did you, can you post test results to make sure the pale tetra isn't due to poor water quality first in ammonia,nitrite,nitrate,and ph, and has the red stripe on the tetra gone real pale.

Unfortunatley I did cycle with them, Lfs didn't advise me otherwise.
The results were posted in last message
The tetra is a really pale red

 

[WILDER]

Sorry didn't notice test results, do you no if the cardinals have been kept with neon tetra's at the lfs.

 

[unclejoes96]

They were in a tank of their own when I bought them

If they haven't been kept with neon tetra's I would say the cycle has took it's toll on the fish and it's immune system has shut down, if you can issolate the fish maybe try anti internal bacteria med, good luck.
