What type of fish can be in brackish water?

Forcing a FW fish to live with any salt at all is unfair to the fish. It will stress it's immune system, causing disease & early death.

i don't soft water species will thrive in brackish water.

HUH??? If you're saying softwater species will thrive in BW, those waters are the exact opposite.

I've seen mollies in saltwater so they might be able to live in brackish water, The Doctor

Yes, molllies are BW fish.

I don't know about all that. What is technically brackish? 1.005?

Its been shown to be beneficial to fish to have a small amount of salt in the water. You can't possibly think that all of the aforementioned fish live in COMPLETELY freshwater environments.

I agree that forcing lets say, a Redtail Catfish, to live in 1.005 or above is wrong. However, throwing a teaspoon or two per gallon to satisfy both an archer fish and a clown loach is not bad at all. It's beneficial to both.

What you can do is maybe add a low salt content in the tank (just enough) and gets some damsels and maybe tank raised clown fish if that's what your trying to do. I know a member on here who has done full saltwater fish and fresh water with some powder that has proteins from salt water and you add it ,it makes it so the two can co exist. I'll find you the thread its really old and got closed..
give me a few and I'll find it.

I read that and it's all well and good.

So when a fish succumbs to ich that may have never been in the water in the first place (all other parameters aside) thats ok right? As long as he wasn't "stressed"???? Kinda self-defeating if you ask me. I read that part. Everyone would LOVE to have a quarantine tank as well. Some of us don't. I just happened to lose 98% of the stock in my tank to a bad case of velvet (also a salt-susceptible parasite) with otherwise PERFECT water parameters. I was able to save the last fish by adding salt which alas...happens to be a L200 Pleco. Who by the way, is more voracious and active than ever.

There's so many variables my friend. Everyone would love to think that we know it all based on this and that scientific study.

Where's the proof the fish are actually stressed by a negligible amount of salt in the water? Show me that all other factors aside, fish with some salt in their water life shorter lives than those without?

You really can't. I've also been a fisherman since I would walk. I've seen saltwater fish in almost pure fresh and freshwater fish in VERY salty water. Why those fish were there...cleaning parasites, spawning, who knows...they were there though.

So for me...I'll take the precaution and add a little salt here and there.
