sick arowana

[Bota]

hi my Arowana is off his feed and his poop is pale yellow.
I found a big dead wooly decorated synadontis under the driftwood a few days ago;maybe that has something to do with it?
the bottom feeders have been dropping like flies too.

Welcome. I don't know anything about Arowanas but if you post this into the sick fish part of the forum, I'm sure you will get a lot more responses.
