I have a 750 fresh water and plenty of fish in there, mostly aggressive.
Lately some of my fish have been vanishing without a trace.
Some of the fish vanishing off are 5-6 inches in length and some had size on them.
The only culprits I can think of is the Arawana, who usually stay 4 feet above at the top, the Clownknife who stays to himself, or the Watercow Goby who usually hides in the lace rock caves.
There are several very large fish in there, but the three above are the only likely three with mouths big enough....well the Clownknife's mouth is pretty small now that I think of it, although he is very big.
I have a Marble Cat, but is average in size and I don't believe big enough to take down some of the below fish. I do have some little guys in the tank, like red jewel and bumble bee (among others), who are in that tank day in and day out but probably play it safe and hide out in the rocks most of the time.
I've had two Jack Dempseys vanish, at least two banded Midas, several smaller Africans, a tropheaus.
