I have a Malawi cichlid that appears to have a tumour on his head. It started growing a few months ago and there are now three distinct pinky white lumps that have burst out of his scales. I am not sure if it is a benign tumour or the cauliflower disease that I have heard of but as I can find no pictures of either it is very difficult. He is still swimming around and not hiding but I cannot see him eating for the last few days, although he doesn't look thin yet. The lumps seem to get caught on the rocks and tear. The last two days his lips seem to be protruding (though I have seen my other african cichlids do this from time to time, but they always go back to normal). None of the other fish are affected. The tank consists of a variety of Malawi species plus two synodontis catfish. The water I use is RO with minerals added. The 290 litre tank has nil nitrite, and nitrates vary but I try to keep them down with frequent water changes (about three buckets every three days very roughly).
I am worried that he is suffering.
