is there a trick to getting them?

[Lord Drakelord]

we have had the Aquarium since 2005, mainly to get the MiBs and have never gotton one of the HUGE sea shells, yet I see them for sale on Luna vendors all the time, what the secret for getting one?

Surely, after nearly 2 and a half years, the odds by now we would have gotten a sea shell as an event or reward in the tank?

 

[Frarc]

You need a full aquarium for the sea shells as rewards.

 

[Lord Drakelord]

You need a full aquarium for the sea shells as rewards.

By full you mean with live fish or can we toss some deco items in as well to make it full?
