I've got one you can cross of your list (redwolf fish) my jardini ate my second 8/9" one two days ago
I should have known he ate one that was 6" few months back but he's been fine with the other since that happened they were swimming together for a while but then he decided enough was enough and bye bye wolf fish
I've got a Flowerhorn, black shark and barramundi in with my jardini. the Jardini is by far the biggest fish in the tank at around 18" and the only aggression is from the black shark.
