my advice is......dont keep an 20" wyckii with a 9" arowana is all i can say.
was told they would be fine as the arowana is a good size and stays at the top. the wyckii had not touched the 2x synodontis both 9" or the green terror 5/6" and he hardly comes out of his pipe/cave, pretty much only half out when being hand fed.
however came home last night after having the aro for four days, and was gone.. no trace, checked the floor due to aro' reputation for jumping /houdini acts, but hefty wooden lid still on, contrays still in place and no sign of the aro on the floor. leaves me to one conclusion.......... bad bad wyckii.
i guess rookie mistake, take others warnings maverick has it right
"
very agressive and predatory. should not be kept with anything you hold dear, most definately just give this fish the whole tank to itself"
am gutted, do love my wyckii, but wanted an aro for ages.
