Shubunkin tails

[khoifish89]

I have 6 shubunkin in a 55 gallon tank. I have notice that about couple month ago that 3 out of the 6 shubunkin tails are shredded or ripped. However, they are all healthy actively swimming and eating. I have two Aquaclear 55 filter (aka 110 model). What is wrong with my shubunkins?

Parameters (amm, nitrite, nitrate, ph)? Water change schedule (%/#wk)? How big are they? We need some more info in order to be able to help.

i would do a test and post the result.

here are the test results for my shubunkin tank

NH3/NH4 (Amomonia) : 0 ppm
NO2- (Nitrite): 0 ppm
NO3 (Nitrate): 0 ppm
pH: 6.0

Your ph is way too low for goldies. 6 is the low limit for the API test and your ph may very well be much lower than 6. The acidic environment is destroying their slime coat and allowing tissue to be destroyed as well as allowing bacteria to invade. Usually, ph is not concern as long as its stable but its one of two likely factors here. The other issue would be simply aggression/nipping from all these guys being in this tank together.

the shred tail does not show sign of bacteria infection though.

Address the low ph and see if there's any improvement. If aggression is contributing to the issue, you will need to figure out how to address it. Are these guys going into your pond in the spring?
