Glenn, yep, the antibiotics for veterinary and fish are the same as for "us". Much cheaper too! Vets have a "medical super glue", Nexaband that is great for gluing yourself back together. Off the shelf super glue works but for those less brave Nexaband is made for gluing tissue. I used to keep a vial around but now just use good old "Crazy Glue" if needed.
No one reading this should take this as me suggesting you practice medicine on yourself! Or that I am giving medical advice! I always consult my vet before I do anything and you should too.
