My question is when do we transition from BBS to pellets for betta fry ? or BBS to something else ? I've done some searching on the internet and some suggest around 4 weeks. I have tried and they wont touch it at all..... I crush up NLS or any other suggestion of brands that they might like. Right now i'm going between microworms and BBS i'm not running low on food but i want to transition them to regular food that is all any suggestions ?
