My betta P.K. isn't eating at night anymore. Today he didn't want to eat at all and his fast isn't until Saturday (I fast him every once and a while to make sure there's no "backup"). I know bettas can get depressed. he's giving me the symptoms of his "I want to be cleaned" sorta thing but I cleaned his tank/bowl recently. I'm saving up for a bigger tank for him, right now he only has a 2 or 3 L bowl. Could he be bored? One thing I was wondering is if I changed the scenery around his bowl, could that interest him a bit more? I know I should invest more into betta care, but I try my best. One thing I do is I keep the room warmer and do what I can to keep the water warm during the day and let it cool a bit at night. One of the first things on my betta to-do list is to get a proper heating system going for him. One other thing, I found my betta moving his rocks around to make almost a wall where the most open space of his scenery is. Is that normal? I know this is excessively long-winded. My biggest concern is that he'll let himself starve to death. Thanks for all and any help guys, I really appreciate it.
