I give mine a variety of pellets, (NLS) frozen/FD bloodworms, tropical flakes, frozen daphnia, shrimp pellets, and sometimes algae wafers. Okay, I don't really give them shrimp pellets and wafers, they usually steal some of the cories' food. Lol.
Just an alert to the other people who are looking at this thread. The pellets by Hikari, Aqueon, Wardley, Top Fin, and Tetra are horrible quality. It's not about "natural ingredients" that they say on the front. Look for protein based ingredients, (i.e. whole halibut meal) instead of cheap protein boosters. (i.e. wheat gluten) You can see that they hardly have any of those. Look at the first 3 ingredients, see what I mean. Hikari used to be the best but they switched it over to the bad side. Some of the BEST ONES are New Life Spectrum, Golden Pearl, Omega One, and Attison's Betta Pro. They discontinued the Pro however, I *think* the Betta Food is okayish..
Over hundreds of bettas die in their small, dirty cups each day. Only you can help them live. Research and then save them, today!
