I have a betta in a filtered 10 gallon tank with two otos. They have been living with me for about a year, and took up residence in the cycled tank when my older betta died. I do a 50% PWC once a week. Water parameters are ammonia 0, nitrites 0, nitrates <5. Ph is ok. There are two live plants. I just noticed this white area around Tooney's mouth this week. He has been spending more time on the bottom of the tank than usual. Is this something I (a newbie) need to know about? Thanks!
