This is a bit sad isnt it!. I saw this thread and decided to pluck all 150 of them out of my polystyrene in the fish house and hand them to my 7 year old daughter to carefully arrange on my Juwel aquarium lid,kept her out of trouble for a while.I gave some of the biggest ones to friends,some were 15cm long,they were off a large male Otorongo ray i had many years ago.
