Blennies:  Notes From Penny:  Overall these fish are some of the most beloved in the hobby due to their beauty & BIG personalities.  Be aware that some are venomous as is noted by the symbol.  These species are peaceful & non-aggressive to humans but if bothered by a tank mate they will open their mouths wide & "display" their venomous fangs.  This is usually enough to deter any fish from pestering them.  ;)  Most are herbivores but also love Mysis Shrimp & Cyclopeez & will learn to eat flake.  Easy to keep & a beautiful addition to any reef tank.
