so im still new in the fh world, i was wondering how much should i feed my lil bonzai fh, he is only 2'', i was feeding him about 3 grand sumo pellets in the morning, and evening, but he would always turn dark whenever i approached him or he saw me looking at him, so i decided to feed him another 5 pellets and after that he seem to not be so stressed about me around him! can someone tell me whats the usual amount to feed fh?
