I have a 5 gal plastic tank, light hood, real plants, filter, bubbler, and will be adding a heater soon. Yesterday I added a new backdrop to the backside of tank (aquamarine theme: plants, no fish picās), but it made my betta flare all day. I know flaring is healthy - in moderation - but I donāt want to tire/stress him. Today I removed the scene and now his nose is pressed against the plastic waiting for underworld to reappear. Will he adjust to backdrop?
