FW to SW and Back Again?

[Oddball]

There are fish that can transit from full freshwater to full marine conditions, on a regular (non-migratory) basis. The term for this propensity is Amphidromous. Here's the place to list the species that have this ability. I'll start it off:

Dormitator maculatus - Jade Goby

*raise hand* i got a question

just wanna clarify...so these fish can go back n forth BUT still you have to do it gradually right? you cant just take it outta ur fresh tank n dump it in ur reef tank, right?

 

[Oddball]

That's the case. Although, there are species that can make the transition faster than others.
