Sick cory - any ideas anyone?
Just over a week ago, I lost one of my peppered corys. After water testing and looking at everything that 'might' have caused it, I put it down to 'one of those things' as the cory had shown no symptoms prior to his death.
Anyway, over the past few days another of my peppereds is causing me concern. He's developed a pink patch on one side of his body - which looks like a sore of some kind. Apart from the mark he is showing no signs of illness - digging about in the sand as usual and feeding well.
Water params fine: constant readings of ammonia 0, nitrite 0, nitrate 5 and pH 6.8.
I've had this group of corys for around a year. Does anyone have any idea what this could be, and would melafix be my best option?
