A clarification: When I said "I usually feed very little, 4 tiny pellets once a day, skipping a day here and there" I meant before she was sick I feed her betta-pellets once daily, skipping days every so often.

With this belly issue, I have fed her peas three times since Monday. Each time a very small amount, maybe 1/4 of a shelled baby pea or less.

Another piece of information: her swimming skills do not seem to be affected. (I had a male betta before her who had swim bladder and therefore swimming issues.)

Thanks again!
