I wasn't given any payment options? I hit purchase...confirmed it, and I got an email with MVPs email. Told me to pay him. I emailed him, and am waiting. Will I get an email saying how to pay? I have a Paypal account, but I'm not very good with it. It's interesting you mentioned columnarus. I had a golden marble die (only fish I actually "lost" that I tried to save) with similar symptoms. That was over 6 months ago, in a different tank. When he died, I stopped medicating. The other fish lived. They were angels also. Can they be carriers? This long after, in a diff tank? Also, I think I remember everyone telling me it couldn't be columnarus, because its more a cold water problem. I keep my tank above 80....always. I wish someone would see my pics, say "oh...it's ******. I cured my fish with this med. I love angelfish and rams. But every time they get a little big, they either stop growing, or get sick. I bend over backwards trying to make the perfect tank for them, but I fail. Then, I watch others never even change their water....and have beautiful, big fish! Maybe it's just me. either way, if anyone can help....I'm listening.
