I haven't seen any disturbances thus far, and I did boil the smaller pieces before I added them.
IME with mopani wood (all I can buy locally) is that it may or may not develop a fungus on it. I have had some that never had any and other pieces I had to boil and scrubb numerous times. I have never had any toxic fungus from it. Though there has been a couple if p here that have. Best advice is just to watch the piece of wood and see if anything grows on it and go from there. If you don't see anything on the pieces you have now I would leave them in there for now tbh but that's my opinion. If you are worried about by all means take them out.

I've had bad experiences with mopani (white fluffy fungus that would not come off) and good results with the dark brown driftwood (whatever it's called :)

I boiled both pieces (seperately) for at least 4 hours and let it sit in water for a day after that before adding them to the tanks.

Animal testing is a terrible idea; they get all nervous and give the wrong answers.

Update time:
Both fish are still in the Hospital Tank, it's had 4 X 50% Water Changes so there should be minimal salts left in it.
The Betta seems back to his old self , he is having a good time keeping an eye on the pleco.
The Pleco's color is much better, but he was hanging on the stone that the airstone is attached to, with his gills in the bubble stream this morning.
He was occasionally dashing up to the surface for gasps of air last night, haven't seen him do it this morning.
We taped a piece of paper over one of the front corners of the tank so he would have somewhere to hide.

Thanks for all the input folks, it's been very helpful.

I agree with the wood suggestions from the two members. And i am glad to hear the fish are responding to the water changes; this confirms my surmise that the issue was the wood fungus.

Update:
Everyone seems to have regressed quite badly.
The Betta keeps wedging himself under the heater, I thought it was due to the current from the airstone I have in the hospital tank.
I got the main tank all cleaned out, set it back up and tried to put the betta in it.
He sank to the bottom and sat there half on his side, respiring heavily.
He eventually went to the surface for a breath, and then he kind of sank down again, but when he touched anything he would lurch to the side like something bit him.
The pleco has been laying on the floor of the hospital tank, not moving. I thought he was dead, but he moved when I touched him.
I did just see him run to the top of the tank for a breath.

Based on this regression I'm going to slowly add Epsom Salts back to the hospital tank and see how we fare.
I'm afraid that whatever happened I did not catch it in time.

Considering how they were improving in post #13, this is a bit scary. It is possible the toxin from the fungus is in the tank attached to this or that. That would explain the Betta regressing when re-introduced. But the pleco acting oddly in the other tank is another matter. Check water parameters between tap and tank, as sudden shocks can be trouble. And you did use a dechlorinator? Even double strength won't hurt.

I did use extra dechlorinator.
The betta went limp as soon as I put him in the tank, and the pleco never left the hospital tank.
The only change there was the removal of the salts.
I've added the salts back into the hospital tank at half strength, and they both seem a bit perkier.

I'm at a loss.
If there is some unknown toxin in the tank how do I remove it?
I pulled all the plants but the sword and rinsed them in hot water straight from the tap, then filled the tank with hot water from the tap and let it run over night with a brand new carbon filter.
I then did a 100% water change, scrubbed down the glass, refilled with treated water.

The betta's jinking when he touched things in the tank and the pleco's sitting in the bubble stream seem to indicate nitrite poisoning.
One of the treatments for this is salts in the water, they both seem happier with the Epsom Salts in the water, so I'm going to go with that for now I think.
I'll up the concentration in the morning.

For what it's worth, here's my experience with mopani wood. I had it in my tank, when I got started with the fish keeping thing. I found one day it had a cottony white substance all over it. Googled it, and read it was completely safe, but snails would eat it. Purchased an apple snail, and sure enough it ate it all. I had no problems ever with the wood.

After reading Byron's comments, awhile back, and some others about the wood, I decided it wasn't worth taking the chance, with my German Blue Rams, that were in that tank. The wood is now in the tank of our Leopard Gecko. I use that malaysian drift wood now, exclusively.

Love to learn what is causing you the problems. Keep up the diligent work!

The Pleco has died.
The betta is listless, but ate pellets this morning.
Baffled and added the filter for the hospital tank with the carbon pad in it.
Very bummed.

If i read everything correctly, you said the betta went limp as soon as it touched the water? Perhaps it is shock? Did you re-acclimate him to the tank properly? Difference in tank temps and water chemistry could cause fish to go into shock.
