Refreshing this thread because I'm thinking about trying to add another jawfish on Friday and want to know what you guys think in light of this thread.
I talked to the biologist at my LFS
recently about reasons why the jawfish may have died and he concluded that it was most likely caused by a lack of Oxygen especially at night. He said that many "unknown" deaths occurring to bottom dwellers most frequently are at least in part caused by a lack of oxygen.
I also took into consideration that there may have been added stress from the clowns bullying him. Their aggression was heightened because they were hosting an anemone which I removed today for numerous reasons.
I'm wondering if the removal of the anemone in conjunction with creating more flow from the top of the tank downward and adding an aerator in the sump would give us confidence in entertaining the idea of trying again with another Jawfish.
