Convict cichlid has small white lumps on body
I have a male convict cichlid that is about 6.5 years old. Just over a week ago, I noticed a small white mark on his body near the left pectoral fin. It got larger until it was protruding from his body. This morning, I noticed another lump on his head on the same side. They donít look fuzzy, and while his colouration seems a bit more patchy than usual, I donít think its ich. Iím currently treating the water with Pimafix, and Iíve also added a bit of aquarium salt. Itís possible he injured himself on a decoration, which I removed today.
He also looks slightly bloated, and has seemed a bit unbalanced when swimming, sometimes his back. Could I get some help identifying what this is, and what should I do to treat it? Thanks.
(I've attached photos of what the white marks/lumps look like. The first one was taken today, the other 2 were taken 2 days ago.)
