I sent a few pics of the growth to a biologist at UH Manoa today. It appears to be an aggressive tumor from my description of it. Ofcourse, I will need to bring my betta in for an exam for the proffessor to know for sure. I am in a dilemma over this. I am attached to my betta. I started this new hobby believing I wouldn't be too emotionally invested in a creature I can't hold or nuzzle with. Boy, was I wrong. I am desperate to do anything for Zuma, to increase his quality of life. However, I dont want a procedure to abruptly end his life or mess with his good attitude. I just can't have pets because I have hard time coping with losing them or dealing with any pain or suffering....but that's for a different forum.
There is very little info out there about using CS on fish, but yes colloidal is a miracle cure for so many ailments in humans and animals. I get mine from a reputable lab. The blue that you mention is not from pharmaceutical grade silver and made by questionable processing methods.
I bring up the question here on this forum because someone posted the use of CS in an aquarium. I googled a search and it brought me here. Except I can't recall the username and it wasnt a recent post. Mysteriously I can't find that info when I googled it again or in my history pages. I was hoping the person sees my post to answer it, but that only happens to lucky people with tumor-free fish.
