toadstool is a great starter coral! IMO, you have to try really hard to kill them lol
Med/high light (I have LEDs so Im not sure about other lighting types) and med to med/high flow. Mine wont open up without a decent amount of flow hitting it. Also, the brown ones are a lot easier. I picked the tyree green for my first one and it doesnt open as much as a brown one but its just soooo pretty lol
Expect it not to open for a week or two after you put it in your system. Some open right away though.
I havent experienced many cons...I would say the biggest one is that when it gets irritated it will shed which means it sucks all the poylps inside and gets a waxy look to it. It will go away. Mine is currently shedding-been about 3 days.
Pros-it just looks cool lol Im an acan/nem type of lady but this guys are unique for sure
