I have a blue ram with a fungal infection (I think). It is a white cottony-looking oval shaped spot about 1/4 inch long on the side of his body. Doesn't look like Ich, because it's localized in one spot. The other blue ram has a split in his dorsal fin that has widened and has white, frayed edges. I have purchased Binox. I plan to remove the carbon from my filter and dose tonight. I'm wondering if I should remove my bio-wheel during treatment. I'd rather not, since I obviously need the biological filtration. Also, the tank is only about 6 weeks old, and I don't want to kill the bio filter just as it is getting established (I cycled with bio-spira). These rams are very delicate it seems. My other fish look and act very healthy.
