Hello, I am new to the site and I have a question about my Florida spotted gar. He's just over 7 inches long and living in a 75 gallon tank for now. I've just recently got a 13" freshwater moray eel. I've done some research on the eel and found that they're more comfortable living in brackish water with salinity levels around 1.005 to 1.010. I was just wondering if this would be too salty for the gar. Ive never added salt before to my tank so I'm still trying to understand it. There's also a 3 inch tiger Oscar, and a sun catfish in the tank. Would they be okay too? If not what would be a suitable salinity the gar and others to be in? Some salt is better than none for the eel.
