There is no ABSOLUTE like that in nature. The fish can exist in any salinity of water measuring from true fresh all the way to true salt in nature. There's no reason they can't adapt to simply living in one single type of water permanently, without any ill side effects. If that were true, you couldn't just keep them in brackish water either, you would have to constantly vary the salinity between fresh and salt to mimic their natural transitioning between them in nature.

The variation seems to be what induces spawning...
By the way, how do you know that? Are you a biologist? Have you done some kind of experiment to demonstrate that they'll survive just as long in FW as brackish? You've only had yours for a year. They can live for over ten years. You can ignore the truth, but the fish will be the one that pays the price.

Keep in mind there are 3 different species of Violet Gobies.. All of them live in BW, one can live in FW, one can live in SW, one is only BW for the full duration of their life.
Hard water will also allow some violet gobies to thrive in FW.

Actually I am a biologist. I admit I haven't worked with this specific goby before keeping it as a pet, but I am fairly educated about fish in general. This isn't specifically related, but I even spent the summer up in Alaska on fishing trawlers cataloging their catch, the environment pulled from, condition, stomach contents, etc.
I will concede that I don't know for sure that eventually mine (and others) won't begin having ill effects from not being moved into brackish water, but my point was that you can't make an absolute claim like that, because it will inevitably be proved false by someone. If I do end up being wrong about this, I will gladly admit it because it will allow me to be a better fishkeeper in the long run. I'm just waiting for evidence that I'm wrong.

I see. It would be very interesting if somebody did an experiment like that though. It would also be very costly because it would take several tanks and this species needs a large tank.
I think the FW species the other person was referring to was Gobioides peruanus. The SW could be either of the other two, but I doubt that it's the one we're talking about (Gobioides broussonnetii)
If you do find that your goby becomes ill and/or dies for no other apparent reason besides being kept in FW, please tell us. Also watch out for the red tumors that have been mentioned so many times by people who've kept violet gobies in FW.

That would be a cool experiment. I don't think my gf would be happy with me setting up 2 more (or three, for sw, bw and fw) and trying it out
. Maybe sometime in the future.
I'll be sure to let anyone know if I start having problems with him. He was the first fish I ever bought, so I'd really be pissed at myself if I let him come to harm because of that.
I couldn't tell you exactly which species mine is, although from looking at a bunch of pics online, it looks more like the Gobioides peruanus. hard to know for sure though, since the physical differences are so slight.

Yeah that's a huge problem if FW does kill them. It doesn't happen for years so people really get attached to them and then they just die.
I think a more conclusive experiment would involve more than 3 tanks. You have to use more than 1 goby for each because one might just be prone to disease or have a parasite already. You have to use multiple tanks because something might happen accidentally in one and kill all the fish inside. The experiment could take years to complete and cost hundreds of dollars.
Ugh.

Ive seen people keep them in totaly fresh all their lifes and some shops i have seen have put stickers next to them saying they are fresh?? Just thought id say it.
