I have watched my betta's tumor grow for about a month, and now it is breaking through the skin -a bubble shaped tumor/blister.
I would like a professional advice on what to do.
I have used antibiotics with no results.
Is surgery possible (with razor blade, like they do it on goldfish) to remove the tumor?
Although the tumor/blister seems to be clear (see through) could I suck it out with a syringe?
