To be honest, I'm just as new to these fish as you. I don't really have any knowledge about their growth rates and preferred parameters but I keep my temp at 82 degress F. Thai blue mahseers are tropical so anything in the range of 80-84 should suffice. All I know is that they're from clean, fast flowing streams and rivers in the wild. I have a lot of flow in the tank and they enjoy it. In my opinion, they're not picky with parameters as long as water is pristine. I don't test my water parameters at all and they're doing great. Very hardy fish but I read that it's a must to add dechlorinator right after taking out the water and while adding water back to the tank during a water change. I change about 40%-50% a week. They're not too picky with food, I'm feeding them hikari lionhead sinking goldfish pellets and hikari sinking carnivore pellets. There's not a whole lot of info about mahseers on the net so I will try my best to document their growth and share it with you guys.
