Blue/Yellow Grouper

(Epinephelus flavocaeruleus)

Epinephelus Groupers should only be added to very large well established aquariums with plenty of rockwork with caves and crevices to hide in. Groupers are very secretive and will hide until food is presented. They have low metabolism's and only require feeding every other day. Groupers are usually very friendly fish except to fish or crustaceans they can fit in their mouth. Should be housed with larger peaceful tank mates and only one grouper per aquarium. Provide a diet of meaty enriched foods. If not eating offer live foods such as enriched Brine, Glass/Grass shrimp, black worms and fiddler crabs to entice a feeding response. Groupers emit large amounts of waste ensure the filtration system can handle the waste.

Blue/Yellow Grouper are also sometimes known as the Redbnded Grouper, Blacktip, Footballer, Redbarred, Scarlet Rock or Weathered Rock Cod. Not often seen in the aquarium trade. Blue/Yellow Groupers are an overall blue violet to gray blue color with light blue spots, bright yellow fins and jaw. As the fish begins to mature the yellow color begins to fade with larger adults typically being dark gray, blue, purple, red brown to almost black. Blue/Yellow Groupers can grow to a little over 35" however are more commonly seen at around 18".

We recommend a minimum aquarium size of 300 gallons or larger for this species.
