The condition of a bladder open to the esophagus is called physostome, the closed condition physoclist. In the latter, the gas content of the bladder is controlled through the rete mirabilis, a network of blood vessels effecting gas exchange between the bladder and the blood. [49] In some fish, a rete mirabile fills the swim bladder with oxygen.
Bettas are susceptible to overfeeding, which can lead to obesity, constipation, swim bladder disease, and other health problems; excessive food may also pollute the water. It is generally advised to feed a betta at least once daily, with only the amount of food it can eat within 3–5 minutes; leftover food should be removed. [29]
