Fish Spotlight – The Whitecap Goby, Lotilia graciliosa

The Whitecap is the common name for Lotilia graciliosa but their is nothing common about this beautiful little commensal fish. Rarely seen in the trade, Lotilia graciliosa or Whitecap is aptly named for it’s white cap that stretches from the upper lip to the dorsal fin.  Often consider the “Holy Grail” for goby lovers, the Whitecap is rarely seen in the hobby.  On doing a search for information on the species, we noticed that there were several references to this fish back in 2010.  At that time, only a few were available and they fetched a very hefty price of $900.00 for a fish that only grows to about 1 3/4″ in length.  Pricing and availability have slightly improved since 2010 but this fish is still considered a rare find
