If you haven't been testing the water, how do yo know it's cycled? In 5 weeks the water can go from ok to deadly.
the water is not direct from tap, it came from my other tank. my fishes there has grown from 10"to 20" in the past few years, so i assumed it is cycled.
i do water change regularly for my tanks. if the water is deadly how can my mbu puffer grow from 5" to 6".
i dont think mbu puffer is hardy fish, if there is something wrong with water then he should first have cloudy eyes, and symptoms throught out his skin.
well, let me put it this way...
can you say that all physically healthy MBU puffer should be active without any exception....
