My betta is acting strange! He’s always by the heater and doesn’t move at all, we try to get him to move but he refuses, I don’t even think he ate last feeding day. My tank is 3 gallon half moon tank. We have everything but we are waiting for my filter pump to be delivered. He has white spots all over him now as if they are blisters... I’m so worried. My other Betta isn’t like that at all. The water in the tank is warm too so I don’t know why he’s acting weird..... here are some pics[you might need to up the brightness]
