[Pea puffer and paracleanse]

I am treating a new pea puffer I got for parasites, it was lethargic and not eating well. I gave it the first dose of paracleanse on Tuesday. I forgot to get the 3rd day dose in yesterday. He is already much more active and eating better. Is it ok to give the 2nd dose a day late or should I just do the water change tomorrow and then repeat in a few weeks for the eggs this round won't kill anyway? 

[Moss propagation and glued anubias?]

I have a floating Christmas moss ball and want to put some of the moss in other parts of the tank. The moss has grown really well and is very bushy. Can I just cut off some of the extra moss and place it where I want? I also have a anubias nana that I crazy glued to a piece of wood by the rhyzome. Its bonded very well to the wood. Is there any way to pull it off without too much damage?

[Purchasing fish online.]

I ordered fish online about 2 weeks ago. Was supposed to be a m/f redneck apisto pair. I think they sent me 2 males. Anyone have experience with this happening, mabey what I can expect from the seller? I sent them a email today but have not heard back. I am  just trying to get an idea what I should expect.
