Just wondering if I should soak their freeze-dried bloodworms too? I also lost 2 Bettas (RIP Finny and Flash) to the internal bacterial problem due to constipation, because back then I had no idea that the pellets were bad... but I did start noticing after they passed away that my remainding Betta's are OK with the bloodworms. Last night though, Flame got bloated again, I don't know why so I will try soaking them from now on and feeding some gel food which I have made for my goldie.
Also, what else is a good diet for Bettas? I have frozen Brine shrimp and mosquito larvae... is that OK? I get a bit paranoid of live food as the local fish store said sometimes they can carry bacteria, and the frozen food I have may be better unless they were very picky or something.
I don't want to lose any more Bettas to the terrible suffering I lost my other two too

Thanks guys!
