My experience as I mentioned was with Flowerhorns and Mammons, they were approx. 12-14 inches and if they came in with a swim bladder issue shallow water quarantine for a couple of days was the fix. It's interesting and good info. to know the same isn't true with Pbass.My experience with swim bladder issues was mostly with large p-bass and not enough water. Once they go sideways in a container its pretty much over for them. And Yes, i use bags inside of totes just for the spill/splash factor. Only types of fish ive had damage them selves in totes are the jumpers… ie. Aros, flagtail, bass… if your containers are good and water tight i dont think the bag offers any advantage for keeping them “safer”… may b benificial to ur sd’s tho. Keep em from hitting the lids. With 14hrs id use as much water as possible. I usually move them half full or less then fill them up further in the car to save my back. Easy to dump water on arrival before u lift again. More water the better for ur goonch also. Id def. B bringing fresh 5gal buckets of tank water for him especially to change through the trip. Ive never used sponges or media on transport, just air. “Bag buddies” used to be popular for shipping. Ive used “ship safe” powder when sending ray pups across the US with no DOA’s… i think it kinda sedates them a bit and keeps the water from fouling. U have more control being able to stop and top off or change water tho i dont think ull need any additives.
I was mistaken about the totes it doesn't say watertight, the cover is held on by handles that snap on as they're pulled up to secure the cover. I'm not sure if I read that about another tote I was considering or totally just or fabricated the whole idea on a assumption. My apologies in case anyone is considering one based on what I said. So, I may use a bag as well for spill/splash issues and for the jumpers as you said. Don't want to start a new fish room with concussed derpy fish.
Stock I'm moving are catfish, bichir, SD's, lungfish, flowerhorn, Gars and a Septemfasciatus gourami. I also chose those totes because they have wheels as my back is 
. Luckily, I've got some help though. I was going to use sponge filters for aeration and some biological filtration and possibly a powerhead for the Goonch or I may rig up something like a spray bar/tubing to maximize surface agitation. I also considered "bag buddies" as you said. I hadn't considered binging extra water but it is probably a good idea especially for the Goonch.
Again thanks
