morning all!
I noticed this morning that my female albino bristlenose has a visible dark patch on her side.....is there something wrong with her intestines? any ideas would be gratefully recieved......she is new to the tank and I had to take a long time to aclimate her her because when I tested the water she came in the nitrates were really high.....the test tube went vivid red .....my nitrates are about 5ppm......even though I took my time aclimating her I am concerned by this dark patch......should I treat for an internal bacterial infection?
