RED RASH ON YELLOW CICHLID

[jrkiwi]

Hi , Im John from New Zealand . I found this great site and thought I would ask re illnesses etc . I have yellow Cichlid which has a red rash around its tail and about 5 mm up its body.

I changed a quarter of the water yesterday or could it be stress as we are having a lot of earthquakes here in New Zealand ?

I look forward to anyones reply

Thanks John
