I asked this once regarding the diet of my Betta, and the feedback was great, I learned alot and the little guy loves his diet plan. So, going to ask for my Otos. I was just letting them eat algae but that's diminishing now. I supplement with blanched zuchini. I recently read they also eat blood worms on occasion - which already is part of my Betta's diet. What about Hikari wafers? Would those make a good staple diet? Or any other suggestions? Thinking that I'll feed them zuchini 1-2 days/wk, bloodworms 1 day/wk, and 4 days / wk.... Hikari wafers? Open to suggestions and if there's better brands, thanks!
