My Aquarium

[Phyrex]

My father has recently taken out everything from his reef aquarium because fish keep on disappearing. Here's what he found to be the cause of it. Those are 1' tiles. If it bites your finger/thumb will swell quite nicely (it's like a bee it leaves the thorns inside the prey, except that it doesn't die).
The whole aquarium is 6'6". The other pics are after he'd fixed the aquarium again.
