Major steps in feeding and overall better chemical balances in synthetic saltwater has made goni's a coral not to fear... Ask me how many have died in my shop....ryhymes with "Hero". Feeding is a huge part of success.. Ask me what my mortaility rate is on green chromis.... why do people buy those? Bangaii Cardinals? Hippo Tangs? Powder Blue's/Browns, Copperbands? Acro's....dont get me started on SPS.
Dont fear the goni's!!! Just ask what you need to take care of them...not an upsell. Tropic Marin, Fauna Marin, Brightwell and Two Little Fishes make great foods that will ensure long term success. I have three service tanks wtih 'em....All three over a year old!
Just some input from a professional insider.
BTW, I have some killer Red's and Outstanding Blues that are doing amazing!
