Hey guys I have a concern about my betta, the last two days it hasn't been able to open it's mouth enough to eat the pellets that I usually feed it and I noticed a bump under it's gills that I don't remember being there. I've tried crushing the pellets but he doesn't seem interested in that so right now he's just not eating does anybody know what could be causing this?
