What Is This Thornlike Growth?

[loohoo313]

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.

that looks like what my angels had
and that turned out to be eye flukes Diplostomum
if left untreated both eyes will be destroyed.


I treated with formalin (1ml per 30 litres for 5 days) but one of the angels still lost an eye and one still has some nodules on its eye.

I'm not sure that bettas will be safe at that dose of formalin
so best air on the side of caution and half dose for twice as long.

Also with formalin you need additional airation running as it eats up O2
like it was food.
