Huh?!? He seems very healthy and active in the brackish tank.
It's odd that the supplier would have them in Brackish if they aren't supposed to be. (This is a high-end dealer and I like to think they know what they are doing!)
Not to mention several references I looked at said "either, or"
If I do switch him over, I will likely convert him by just doing small water changes without replacing the salt. (He's alone in that tank)
Thanks, and don't stop replying. I love the input here!
