| Re: Ich Immunity
Kathy, it's hard to say. I would imagine they are based on my observations of fish in the sea. Moorish Idols for instance swim in large arcs around the reef visiting the same areas over and over again looking for food. I would imagine that if you were to collect that Idol and put it in a tank it would still look for that same route around the reef. If it was tank raised, that route around the reef would not be ingrained in it and it may be more used to hitting glass every few inches. Some sharks swim hundreds and sometimes thousands of miles every year on the same route and American eels swim across the Atlantic ocean to spawn where they were spawned. Salmon swim to the same stream where they were born.
These fish may fare better in a tank if they were raised there and have no ingrained knowledge of these areas.
Of course these are my opinions and not based on anything except my years of diving with these fish.
