His fins are frayed now but no one is biting/ harrasing him. I just did a 40% water change because I don’t know what else to do everyone else in the tank (bowfin, endlichri, green phantom pleco) are all doing fine.

I just tested my water and it came back with high levels of nitrate and about .50 ppm of ammonia... I instantly ran to the pet store for ammonia lock but the pet store was closed I’m going first thing in the morning I just hope it’s not to late for the little guy.

Sorry to hear that; too late to help, I know, but the next time you notice a potential problem you should test the water right away, rather than the following day. If you get a reading like that you should run to the hose to do a water change, not to the store for a solution.

When you have bad water...get rid of it and replace it with good water immediately. Then track down the source of the original problem and correct it so the issue doesn't recur. In this case we don't know where the ammonia spike came from but maybe if you retrace all your steps the source might become apparent. High nitrates in a tank that was presumably filled with fresh water only two weeks ago would seem to indicate that the cycle was preserved by utilizing the mature media. It also is a hint that you need to change more water more frequently. But the ammonia spike in a cycled tank is puzzling. Dead fish? Extreme overfeeding? Did you add a bunch of other fish at the same time as the Arowana? Any of those things might have temporarily overwhelmed the capacity of the biofilter to completely process a spike.

If you already have a bottle of something to detox/lock the ammonia right there on the shelf, that might be the fastest and most immediate bandaid to apply; maybe get some product and keep it on hand for future problems. But keep the hose handy!

There's been one in the lfs for months in a top tank under absolutely blaring lights. He looks like he's slowly being driven insane. Even if I could, I wouldn't take it home.
