Sorry he looked pretty bad. Any tankmates beating on him? He looked really stressed. With the skin and fin lesions I suspect he went septic

In a FB Group this morning someone posted about a weird thing he saw in his tank. He also happens to have an Arowana. I saw the same thing a week before my Arowana died. One guy mentioned that the Aro may be sick. I didn't take a photo of mine, I actually thought mine was part of the zucchini the plecos were eating but then again it didn't look like part of it so I just scooped it out. This may be a clue that I totally missed. View attachment 1224010 View attachment 1224011
