I've kept a baby cuttlefish before too, but its long gone now.

Lemme hunt for his pic... hidden somewhere in one of the folders in
my comp..
Ah, here he is!

I'm ashamed to say he was the result of my impulse purchase when i
was just starting to keep marine creatures.. i saw it in a fish
farm, thought it was very cute, and bought it even though i had not
done any research on it. For that matter, i did not even have a
proper tank for him (as he turned out to be too predatory to house
with any other marine creature), and hence had to house him in the
quarantine tank (which is on the floor as you can see from the
pic).
Real fascinating fellow who exhibits a dazzling colour change
whenever he is excited (on spotting his dinner of live shrimps or
feeder fishes or when i go too near his tank). Interesting to watch
him stalk his prey then suck them up by shooting out 2 long
tentacles at lightning speed.
Not sure what killed him eventually as water parameters were
stable... it just went off-feed for several days, inked in his tank
several times and died. When i came home that day, the tank stank
of fishy sotong.
