Cephalopholis Argus

gallery/eos back on rocks


good old habits coming back

EOS found several good reasons to adopt new rest areas… After spending months at the bottom or hanging head down from the auxiliary biological filters in the corners… Looking in despair at the empty rockwork… Something finally made his day !!
One 1/2 inch GSP colony (Briareum Violacea); two new baby Rhodactis Anemones; and three Duncan frags (Duncanopsammia Axifuga) have seemingly brightened his days !!
EOS has now regained interest in his environment and adopted four new resting spots… As you know Groupers have no swim bladder so they spend their days resting on surfaces.

His attitude towards Anemones and Corals is unexpected from such a territorial and  dominant species that would tear apart and engulf most invertebrates !! He actually enjoys being in proximity of his living friends. And probably has this inner sense that they are hiding spots for many of his preys in the wild. Groupers can cooperate with other species when hunting on their territories. They will have Moray Eels and Volitans track or expel preys from crevices and coral formations !! And just like Volitan: Cephalopholis Argus can easily bite off another fish’s mouth so they are best kept to themselves and beware of Forums – FAQ’s – and Comment columns that say otherwise.

No they don’t do fine with any species (except when juvenile) and will not get along fine with Moray Eels and Volitan in captivity !! I have kept all three (including Black Spotted Cat Sharks)… Here’s a glimpse of the situation: Snowflake Eels (for example) wnen they have reached adulthood will eat the shark; eat the Volitan: and eat the Grouper.
Any such species can only be kept as single specimens or a Mated Pair except the Grouper… Volitan females by the way have more white and white lines than males: it allows them to be better seen at night on the reefs when looking for a mate. Two males will fight to the end in captivity….
Don’t even think of mating Groupers in captivity. In the wild: Males have huge territories of several hundred square yards and multiple females: each in it’s lair that they visit regularly…

For Grouper lovers: Cephalopholis Argus is an intelligent choice. It is one of the smallest and is the most abundant fish in nature.. It’s not endangered in any way. They also live several decades so be prepared to care for it at least 40 years !!! Think of it this way: Dobermans have a life expectancy of only 8 to 10 years…   :)
