White flim?

Any idea what this is?? About 3 weeks ago 2 of my Otto fish died and a kinda white film on them but figured they were dead a few days before I noticed them (tank was heavily planted and they like to hide) did many water changes over the past few weeks. I JUST put the droft wood in maybe two days ago after boiling them for a few hours and soaking them for a day. It looks like one of my Otto fish MIGHT have some on him (hard to see as he keeps swimming away and hiding) but my butterfly tetras seems okay?

The whitish slime/fuzz on the wood is a fungus. I wouldn't think this would "grow" on a live fish, but what is on the wood is fungus. Some fungi are harmless to fish, but there are some highly toxic fungi that will kill fish and anything else eating it. There is no way to tell if this particular fungus is or is not toxic, without an exam by a microbiologist.

This may be the cause of the otos deaths, or it may not. The other fish at least in my case showed signs of being poisoned, such as rapid respiration, lethargy (less activity), and death following.

Dead fish often develop fungus (a different species) and that may be what is on the otos, or it may be an increase in slime.

My fish died before I even ordered the new drift wood. I've tested my water levels and everything is in good range. I was going to move my rubber lip in this tank since it's larger and has more driftwood
