Hello. I have recently bought a "baby betta" from Petco, and introduced him to his cycled, filtered, heated 5 gallon. He (I say "he" lightly based on Petco's judgement) is about and inch long, maybe just a milimeter shy, and has been eating 3 Hikari Micro Pellets twice a day and a couple of small brine shrimp per day. Something has come up and I will have to go out of town for about 3 days. I know the adults can handle it easily, but how long can an inch long fry last? Any help will be greatly appreciated.
