Hi, I am looking for some advice. As shown in the pictures, my flowerhorn has just started excreting white lumps. I am not sure if this is normal or if this is the start of an illness. He is eating well and looks to be in full health (no body/fin damage). I have not changed his diet (other than adding a few peas a couple days ago) so I do not think it could be that. Should this be a worry?
