Can anyone tell me what this is? My male swordtail has developed a bump on his back. He is eating, swimming normally and chasing the females as usual. I have had him for 5 months in my well established planted community tank. He is a prolific breeder lol.

Hello everyone,
I'm looking to set up a 75g swordtail biotope, does anyone have any pictures I can look at, or know of any resources I can view? I've looked long and far but can't seem to find anything. Perhaps I'm not looking in the right place.
