So I was testing how long each coral takes to turn into dead coral when I notice that Fire and Horn Coral take a second longer then the Bubble, Brain and Tube.
Here are the amount of Seconds it takes for each coral to dry off
Tube: 3.56 sec
Brain: 3.30 sec
Bubble: 3.70 sec
Fire: 4.98 sec
Horn: 4.52 sec
The Fire and Horn Coral are about a second off from the Tube, Brain and Bubble when they should all die at the same time.
