This is absolutely not a fish your a 14g tank. This fish requires a LOT of LR
and a larger tank. They feed almost entirely on live copepods and will not survive in a tank that small.
There are a lot of people who have the setup with a refugium and a great pod population that can't keep them alive. I am one of those. I have nearly 300lbs of LR
in my system and a large refugium that has been running for almost 3 years now. I have a giant pod population and I'm not going to put that fish in my system at least not for another 6 months.
This is not a beginner fish.
