all this about big aros eating small dats is rubbish
if you mix the aro with small dats from small you wont have many problems
i have had a tank full of 9 monster Asian aros 22inch each in a tank with 4inch dats with no hiding place and it was fine that shows me most if not all aros wont eat dats
many fish know another fish defenses
the dats defense is its very sharp dorsal fin and if a dat was eaten by another fish that dorsal fin would do some very bad internal damage to the fish that eats it
i for one have seen dats attacked but never eaten even my rays sometimes jump on the dats then feel the sharp dorsal fin and let them go
if anyone has had a dat that was eaten i would like to hear what happened to the fish that ate it
