[Captainhemo]

Hi
I keep reading about all these dyed corals and not to buy thme etc etc. Can someone tell us ralitvily new " keepers" what exactly we should be looking for and what corals are most commonly subjected to this practice ? I am ralitively new to all this and have been purchasing some of my first corals. , Now I'm wondering if I've been buying anything that is dyed w/o even knowing it I'd really appreciate any tips/pointere anyone can give regarding what to watch for and any particular coral that maybe dyed

TIA
