I recently purchased a red haddoni online. After QT for a week and a half of no deflating (didn't end up treating), I put it in a tank plumbed into my main system. It appears to be doing fine except that its mouth remains open, and has been nearly the whole time I've had it. Not gaping open, just open. Is this normal adjustment behavior for haddonis? It ended up being much bigger than I expected, so it is sitting in a 40B by itself right now. Thanks for the help!
