I think Ivory is the killer (because they're roommates!)
Let's start from the beginning. We have no ides where he was so let's just say he was in his room. Teal Green went to shower but then he saw the message saying "Meet me at the fish tank". Teal Green went to the fish tank but saw no one there. Ivory was launced a metal ball from the pool and the ball knocked Teal Green into the fish tank. (the ball did some damage too) You can guess what happend next.

scarlet must be killer.
She got the anstheia pills from
Pliner Blue's box of stuff and shoved it in Shamrock's mouth.
Shamrock was walking to the bathroom for 45 minuets and whenhe got there, Sccarlet snuck up behind him and decapitated him, while also stabbing the camera. She cooked the frekin body, and put the head under the tray topper.
Also White was cooked with Shamrock's body.
