hello, i have questions on yellow, naso and powder blue tangs. what is the best food for them. i have in the past had trouble with them and i like thier colors and character however i do not want to spend hard earned money that may be hard to keep alive. i always feel like a bad parent when my fish die. i am not sure if brine shrimp, mysis, are cyclops are what they feed on. i have also tried algae strips but i am not sure how much of that is bad for the tank ( can you overfeed with algae like you can with other foods) thanks in advance for any help here.
