Thanks to Sorrell for the guidance. I have o ammonia and the ph & nitrates are fine, the arowana is in its own tank. This is one hardy little fish. I have been keeping watch over this little guy for the past 4 days. He was laying on his side on barely moving, just lifting his head ever so slightly. I would either swirl the water or put him in the net so that he would move and not just lay there . Each day he has seemed stronger in appearance. I also got some plankton from the fish store and even though he didn't appear to be eating , I figured some of the nutrients had to be absorbed in the water. I have also been changing about 10 percent of the water every day. Today I am happy to report that he has been swimming in a circle on the bottom of the tank all day. He seems to be one sided with his left fin drawn up but when he gets a little elevation the fin comes out. He is also eating, by chance I happen to catch him snapping up some plankton. He even looks much stronger. The only thing is that he is on the bottom of the tank. Is he still suffering the effects of the ammonia?? Does it take time for him to be able sustain himself at the top of the tank?? Is there something I should be doing?? I am amazed that he has not only lasted but that he seems to be recovering. I feel like I have been up with a newborn for the past few days.
