i dont know about this for cuttles or even salt water so DO NOT TRY IT UNTILL IT HAS BEEN DISCUSSED WHATEVER YOU DO - I HAVE NO IDEA WHAT I AM TALKING ABOUT...lol but i used to use mercurachrome on cuts and abrasions on my axolotls ie. when one bit of another's leg lol (kinda lol) However it is a POISON! U would not be able to add it to the water cos you have to let it dry for about 30 seconds - this may not be possible with cuttles...Collin, you know more about both cuttles and axolotls than any of us...help
and dont forget - DO NOT TRY THIS UNTILL IT HAS BEEN DISCUSSED!
