i have a female betta in my 10 gallon tank along with 3 neon tetras, 3 dwarf platys, and 2 ghost shrimps. I feed the ghost shirnp pieces of algae wafers about 3 times a week. today, i noticed that the betta was nibbling on a piece...then swallowed it whole! then she staretd "hiccuping". she seems better now...but...should I be worried?
