i fed mine spirulina brine and gave him the dry seaweed always..like 2 times a day..whole cubes each time..idk i guess some people think thats alot..but tangs have very fast metabolisms..and little ones need to eat more than bigger ones i think..but some say over feeding can lead to ich..i battled that when i had my hippo just like the 2nd week i had him but just kept feeding and put a neon goby and he was fine..just my experience
