Glass catfish red lump around spine

[Goshfush]

Hello does anyone know what this red lump around the spine of my glass catfish is? Has anyone seen this before? Am; 0 Ni;0 Na; 5-10 PH; 7 

tank is about 3 years old and all other fish are fine. I haven’t added any new fish for 6 months. Apart from the lump the body of the fish is getting a lil cloudy. And there is a small white lump on top of the fish.  At this point it seems active and eating.
Anyone know what I should do to help this fish?

Could be an internal growth or a bacterial infection causing inflammation of the surrounding tissue what I would do is quarantine and do a course of kanaplex in food feeding a small amount twice a day for 7 days

Hi Colu thanks so much for that i forgot to mention I’m in Australia and we don’t have access to kanaplex here but we do have access to tetracycline for fish. Do you think I could do the same with that?

Tetracycline would would work it would be more effective in food he's a food recipe you can use with tetracycline@Goshfush
