After some help please. I have a Red Tail Shark which over the last couple of days has gone agrey colour and his fins look more orange than Red. Have tested the water and everything is within acceptable parameters. He gets fed on flakes, wafers or frozen food and also shares veg like courgette with my plec. I do a 30% water change on a weekly basis. Does this mean there is something wrong ?
