hello! after a month of practically eating nothing, my mandarin goby started to take pellets. he has gotten really skinny from the past month, how often should i be feeding him? i have been feeding him 6 - 8 spectrum 1mm pellets about 2 to 3 times a day. I also have a leopard wrasse taking pellets. I've read both fish have a fast metabolism and need constant feeding, is this true?
