bought a new betta a male half moon double tail on saturday afternoon. he ate only once and it was only a single betta pellet right after he got home and has avoided food since. he'll stare at it but swim away. i saw a positive sign this morning, he's made a bubble nest but im still worried since it's been 3 days and that he'll starve himself to death. im thinking about returning him by tomorrow if he doesnt start eating.
he's in a 2.5g tank with a heater, used seachem stability, and api stress coat and stress zyme, and nitrate remover (or was it nitrite, i forget) a soil/gravel bottom along with a rock with java moss on it.
