Hi, I did a quick google search for Bristlenose forums because I'm quite worried about a lump I just noticed on my boy Vegeta's head and I couldn't find any answers elsewhere... so sorry that this is my first post here. Please, can any experts tell me what's wrong with my fella? Is this sinister, contagious, or benign and just a part of fish ageing? I don't have a spare tank to isolate him but nobody is acting sick at all.
I'm new to keeping fish and far from an expert.
The basics that I know are in the spoiler...
Any help would be greatly appreciated, I'm really worried about him and feel like a horrible fish owner.
