Are they frozen or freeze-dried? There are differing opinions on how often to feed bloodworms. I personally feel that as long as you are feeding your betta only one worm per day, he'll be fine. The other two meals can be pellets. Other people feed their bettas one worm a week. It's really up to you.
As long as they are small pieces and not whole worms, I don't think it will hurt him but if you want to be on the safe side, you can cut down to one a day or two every few days. There are some people who have experienced bloat when feeding freeze-dried bloodworms on a regular basis. I mean, their fish have bloated, not the person. I personally haven't had that happen but I have also noticed that my fish don't pass waste as often when I feed them too much dry food like pellets and freeze-dried worms. They go, just not as often so the potential for constipation is there.
Freeze dried foods should only be fed once a week, not once a day. Also, peas are actually not a good food to give bettas. It may help them "loosen up" but it isn't very good for them. They wouldn't normally eat it in the wild and bettas are carnivores. Daphnia is a better option
Yeah, daphnia is the better option for sure but also hard to find. In a pinch, peas won't hurt. The fiber will help them and according to some sources, they obtain moisture from the peas that they don't get from normal food. If Freddy gets constipated, I'd certainly suggest daphnia and epsom salts. But isn't he just listless right now, Bakesale?
Yeah, he's looking a lot better today, he still has trouble getting up sometimes but hes definately more active than he has been, I havn't fed him in 2 days, I noticed he WAS looking just ever so slightly bloated, he still manages to sneak in some of the tetras food though.
Here's a picture of my new tank, only just put the water in so its very murky.
