I have this angelfish with some kind of parasitic infection. I think it could be hextemia from the small signs of hole in the head.
Right now hes lying on his side at the bottom of the tank. Hes progressing quite fast, yesterday he was swimming just fine and now idk if i has the strength to swim. I moved him to my hospital tank where i was going to start treatment.
The only parasitic infection treatment availble to me (live in Canada) is the fritz mardel parashield. Its quite expenive $30CAD.
I dont want to spend the money if it wont work, do you think its too late? Do you think he'll die? Im surprised he survived the night😪.
