Hey guys. I have a 75 gallon 4' tank and am doing some research into what tang or tangs could be a possibility. I had a kole tang for about a month and it died of unknown cause, so I'd rather not try another kole. I see a lot of people with up to several tangs in a tank this size and I also see lots of hatred and holier-than-thou posts when the topic of tangs and tank size comes up on forums. Anyway I have been researching chocolate tangs and it seems most retailers say 50-75 gallons is ok for a chocolate tang. I have a hard time believing this as they can reach 6-8", right? Is there something I am missing? I would love to have a chocolate tang. Curious about anyone's experiences with them. Thanks in advance!
