I did bettas for a while when i was much younger,much younger and less experienced.. it was tough to get them past the fry stage....1 cold breeze across the top of the water they all will perish....the longest i had fry was 3 weeks...sad to watch them all die for the amount of work i put into them...I think I still have some of the supplies at my parents house....hmmmmm maybe i might try again
