Re: freshwater jellyfish??
I just read a article last week on how there are some places that have developed through time freshwater fish that are the same as their saltwater counterparts. They have conditioned them through generations by changing the water mix every generation. Now they are to the point where they are going to release them to the public for their freshwater tanks.
In my mind this is a nightmare. Now people will think they can buy any fish and throw them in any tank.
