Ich, Heat, Salt....and Fish Aggression??

Okay, can someone let me know if this is normal?

My fish have had ich for about 4 or 5 days, I started aquari-sol treatment after the second day and heat and aquarium salt on the third day. The temp hovers between 82 and 84 degrees F and ever since I added the heat and salt to the treatment my Ryukin goldfish has been incessantly nipping at my blackmoor GF. He never did this before but after the heat and salt he does it more and more. Sometimes he even chases him around and keeps nipping.

Is this normal? Is it because of the heat? Or because if the ich (it has gotten worse)? Or because of the aquarium salt? Should I do anything? If so, what?

Thanks in advance!

EDIT: Just to be clear, he isn't like nipping at his fins or tail, he goes and puckers up against his side as if he sees a fish flake on it.

It is a pretty small tank as it is, 2 gallon, do you recommend the divider anyway?

Also, with regard to mating, two questions:

1) Would a ryukin and a blackmoor mate?
2) How can you tell a GF's gender?

Males develop tubercles on their gill covers and surronding area - which BTW, can look more than a bit like Ich...????

Exactly! I have been staring at him for like an hour already, lol! Trying to figure out whether it is ich or tubercles! I believe that they may just be tubercles, they seem to look different from the ich but I am not sure if it is just my imagination.

Also, the tubercles (or ich) is not exactly on his gill covers but rather on his "chin" and "jawbone"....so I am not sure what to make of it.

AND...my ich is getting worse and worse! I am hoping that is a good sign maybe....like the heat, salt, and aquari-sol treatment is speeding up the ich life cycle so they are maturing faster. Does that make sense?
