but what should a good schedule for water changes be?
It will depend on how much your ammonia, nitrite and nitrate pull throughout the process.
 
I think you have a pearlscale and a comet from your other thread. Comets are too big. Your 15g will fit only one pearlscale.
 
i once kept a baby silver arowana in an unfiltered tank for 3 weeks, feeding it blackworms and krill generously and i had to give it away because it grew too large....very healthy fish throught the process

Keeping any fish in an unfiltered tank is a slippery slope.. Very easy for things to go wrong and I wouldn't suggest it ever as a reasonable way to keep fish.
 
Why dont you stick cheap $20 HoB filter with a bio pad in it on the tank....
It'll keep them alive and reasonably healthy after the bio pad grows a bit.

With just an airstone, I'll give them about 2 weeks before the ammonia kills them. Maybe less.
