drive it like you stole it.
NOW, if you have a suggestion on a fish for him, then type so, if not? dont post on the topic.
That's a wee bit rude don't you think?
After all I have the best intrests of the fish first off.
I didn't wish to know the condition of your friend, maybe it sounded like I did after reading that post but as you said your friend has amnesia then I'd definitely say no fish, just my personal opinion.
As you've already stated about this person they bought an arowana so its clear your not constantly with this person otherwise you'd have let him pick a better choice of fish, hopefully.
How about you let your friend in on your fish as your both in the same house? Fedding, water changes ect.
