Jeez, I don't know where to start...No, it is a FW fish. You cannot keep a FW fish in BW, a BW fish in FW, a FW fish in SW or a SW fish in FW.
Well, for starters you can't actually keep a panther grouper in freshwater, bumblebee groupers are a different story though. Bumblebee groupers are 100% euryhaline, and given the right amount of time you can most definitely acclimate a saltwater raised bumblebee grouper to low gravity brackish and have it thrive, and maybe even to freshwater with a drastically shortened lifespan, given they do live for upwards of 40 years naturally, so what's 15 years off, huh? Likewise, you can also acclimate a freshwater farmed or bred bumblebee grouper into brackish or saltwater for some decently desirable results as well.i thought u couldnt keep a panther grouper, or bb grouper in fw. but thats already been proven lol. who knows what you can do untill you try it.

If you take a purely freshwater fish and acclimate it to saltwater, it will survive for a disgustingly short period of time, but if you were to take a low gravity tolerant brackish water fish and acclimate it to saltwater it would survive for maybe around a day. But marble gobies are a completely different fish from the freshwater cichlids and such that you associate with freshwater aquaria in the sense that they're considered brackish water fish, but not euryhaline (meaning they can live in all salt gravities from pure freshwater to marine), marble gobies are river mouth and tributary dwelling fish, so they encounter freshwater and moderately high gravity brackish water and are best kept with a salt gravity of 1.012 or slightly lower, so to answer the OP's question, no, you MOST DEFINITELY CANNOT keep marble gobies in saltwater, but they thrive in freshwater and brackish water.
I doubt they'll listen considering the last post was 11 1/2 years ago lmaoWell, for starters you can't actually keep a panther grouper in freshwater, bumblebee groupers are a different story though.
