I heard its better for a betta in brackish water but i'm not to sure due to them being a tropical fish and all, some say it helps their gils and skin or something on that line but has anyone found or new ish its true or not?
Freshwater aquarium salt DOES NOT create a brackish environment. First, the chemical make up of the salt itself is completely wrong. It contains different minerals. Freshwater aquarium salt is used in restoring electrolytes to the water that fish need and helping prevent/cure infection. Second, if you read the label on the aquarium salt, it says right on it that it is not to be used as a substitute for marine aquarium salt. If you look up how to make a brackish tank, it says to use marine salt. So, basically, by adding aquarium salt to your tank, you ARE NOT creating a brackish environment...at all.
1.001 isn't brackish. Also, Bettas do not just come from rice paddies.
After reading this thread I thought I might give it a try. I already had marine salt. I did a major re-scape in one of my betta tanks that required me to drain the tank. So I've got a 10 gallon tank with a betta in it with a SG of 1.001, I hope this goes well.
My inclination was more of a theoretical desire then a actual experiment. There is no reason to try it in the first place. However, betta have been around longer then rice paddies. The question was simply were splendens around or did they evolve specifically to fresh water rice fields. Could a separate group live outside of the fields and so on. Besides, not all, not even close to all, species of betta actually live in the rice fields, many live outside of them possibly in b brackish conditions. However, as I said earlier, our domestic bettas are NOT a brackish water fish.
