What Is This Thorn Like Growth?

I feel like I am always on this forum asking about a new treatment for my Nemo. Veil tail betta who has been dealing with "something" for better part of two months now. He seems otherwise healthy except for a white spot that remained after what I thought was a bout of fungus. Well, he developed fin and tail rot, so this week, per everyone's advice, I began him on tetracycline. OK, seems to be doing better. Tonight I looked and him and the white spot now looks like a white thorn sticking out. PARASITE Geez, I've treated this fish for everything under the sun. He seems happy and has been bubblenesting like crazy. My husband thinks I am crazy, but he hasn't died yet and I've had him since December. (the fish, not my husband- hehehe) So what do you think it is. I took a picture. Not sure how clear it will come through.

Well fish can get bacterial infections on top of parasites, there is a parasite called a thorny head, take a look.

Can I use a parasite treatment with the tetracycline or should I finish the meds fisrt before starting others?
I've learned a lot along the way here, but I am still ignorant about medications.

What kind of med will work best?

No don't use both meds, do a water change of 30% add carbon for aday then go in with a parasite med if you think it is a parasite, like thorny head parasite.

Are you keeping the tank water clean? If the fish keeps getting sick it's probably from poor water conditions.
