ok so i have been watching my tang for a few days and it had 2 little whit specs on its fins one on the side fin and one on the tail fin. At first i thought it was Ich, so did other people i asked about this..and some people said that garlic can help and so ive been using the Kent Marine Garlic Extreme.. but all the pics i seen that were ich looked to be small white spots on the body and fins.. my tang still only has the 2 spots and seems to have no signs of it being sick. the white spot on its side fin looks to be getting bigger, it looks like a small white ball attached to its fin.. so question is, is this Ich or another kind of parasite.
