By that logic, we can put 3 tangs in a 15 gallon. It’s common sense. Every person that has a tank is hypocritical because their fish are not in the ocean. There is no magical length, but clearly the bigger the better. I say this tank is one of the smallest with the most fish crammed in there. I don’t think I’ve ever seen a tank so overcrowded with the wrong fish in my 20+ years in the hobby and the business.
Nowehere in my posts was that ever implied and I even said "there is absolutely too small"
However, there is no magical number or formula for "what is the right size/length?" They are all made up numbers to justify what size tank we need to keep which fish.
Most people claim an achilles tang can be kept in a 6 foot tank. Yet, talk to anyone that is successful with them and they will all tell you 8 feet is the bare minimum and 10-12 feet is much better and you need WAY more flow than you ever imagined. Why? Becuase that is where they live in the ocean. Super high energy reefs where waves and tides are pulling them in every direction. Why don't we see posts ripping on people who keep them in 6 foot tanks? Because 6 feet is good enough for tangs?
The pile on mob mentality in this thread is crazy. I bet if most on here posted videos of their tanks, we could rip most of them apart for something. Should we? Absolutely not.
