Cant agree with you any more Awi.Matthew here is the problem that most newbies will/do encounter when they "research":
"Not all invertebrates are "reef safe". Many of them will tear up corals, consume fish and otherwise destroy other tank inhabitants. The invertebrates listed below are some (by all means not all) generally considered by experienced reef tank keepers to be safe for reef tanks. Keep in mind that nothing is "foolproof" when it comes to live animals. There are renegades in any species, so if your new tank critter doesn't work out, remove it before it can do serious damage.
Links to each species are included for profiles, information, facts, photos and pictures."
Sally Lightfoot Crab (Percnon gibbesi)
Reef Tank Safe:
Yes, with caution.
Now as a newbie reads the above they will think this crab is safe to put in their tank. Which I for one thought so back in 2001 when I purchased it for my little 30 gallon tank. It ate or killed every single fish in that tank.
BTW, I also stay away from the Coral Banded one as well. Also suppose to be "reef safe with caution".
Had I found during "research" that they could possibly eat or kill fish I would not have purchased either.
Which brings me to; It is Good Thing to have post like these to warn others of worse case scenarios.........:smile:
