Burrfish (Added Picture)

[GreenSpottedPuffer]

Just looking for advice on treating a Burrfish for internal parasites. I know Burrfish so often have IP and it can be hard to treat but I want to give it a shot with this little guy. My LFS has had him for about 2 weeks and he eats everyday but his belly is sooooo sunken. If he was not eating at all, I would not have even tried this. He is actually extremely active and his colors are bright and beautiful. He looks great besides the belly, so I think he still may be relatively healthy all things considered.

I know I should be looking for mads with Metronidazole and/or Levimasole but Im sure if there is a specific one that someone can recommend and maybe advice on treatment. I have an anti-parasite med by Jungle that is suppose to treat IP but I have no idea how well it works. I don't even remember why I have it to be honest. Must have been years ago. Its just little pellets though and Im not sure he will eat pellets but I could mash them into prawn I think.

Anyways, looking for advice in general...he such a beautiful little guy!

Also, can anyone can tell me where the best place to get meds in vancouver would be? I know I can get Metronidazole by seachem at most LFS but they would not have Levimasole I don't think.
