Help, Fishblr! I need advice. This is Black Tulip, my betta fish. I've had him since May. He lives in a divided 10 gallon tank with my first betta, Sushi. For a few days he's be leaning halfway over and sleeping at the top of the tank all day. My roommate was even worried that he was dead. This behavior seems unusual and I just wanted to ask those more knowledgeable about what you think it could be. Sushi the other fish is doing fine in the same tank. He doesn't have the same energy he used to and I'm worried. Thanks for the advice. P.s., it is difficult to take pictures of black fish.
