I think there may be a bit of overmedicating going on here. Pin holes
in the tail are nothing to worry about and will heal themselves in a
couple of days. Even more serious fin rot can often be treated
successfully by increasing your water changes and monitoring your water
parameters. To put an already stressed fish through a course of
antibiotics may add additional stress.

That said, it's important to finish the course of Ich treatment. As you
may or may not know there are three life stages to these parasites and
they are only affected by the medication a couple of days out of the
cycle so if you stop treating the Ich it's very possible you will miss
those days and they will return in greater numbers.

Whether or not you finish the treatment of antibiotics is sort of up to
you. Antibiotics should be followed through because under-medicating or
shortening the course may lead to antibiotic-resistant bacteria. On the
other hand, unnecessary treatment may be harmful to your betta.

I fully agree with IDzine01. = )

Increase water changes, don't rush into medicating, and finish the Ich
meds. I prefer Quick Cure to any other Ich med...even those with the
same ingredients (RidIch and RidIch+) don't seem to work as fast and I
don't know why.
I also treat a full 7 days (bottle says like 3). The life cycle of the
Ich parasite can only be killed at one stage of it's life cycle, and
it's not the stage of white spots you see on the fish either.
This is why a full 7-10 day treatment is needed.
I also will NOT treat with quick cure if a new fish shows a spot or
two. I first do another water change and some salt.
If your water is kept clean, and you catch it fast, and the fish isn't
suffering from anything else that would tax it's immune system, they
99% oif the time fight the little buggers themselves without the need
for harsh medications....which all Ich meds are.
Same with antibiotics...never treat unless you are absolutely sure what
you are treating and that it's the proper antibiotic. Many just treat
gram negative or gram positive strains of bacteria.....and not every
infection is the same, so you really need to know what you are dealing
with before treating.
Some antibiotics are broad spectrum and treat both gram positive and
negative strains of bacterial infections, but again, never treat unless
you are absolutely sure of what it is your fish is fighting.
