any idea of an average lifespan of these. i thought someone had said they have very short life spans.
Frogfish longevity is a depressing topic. If you read the various frogfish forums, you'll come to realize that, for most, captive life of a frogfish can be measured in months. Reefcherie has had her pictus for over two years. I had a commerson for four.
Captive frogfish mortality usually involves systemic disease from a poor diet, bacterial or protozoal infection from lack of quarantine and/or environmental deficiencies, poor tankmate choices ... in the general, the lack of proper captive care.
I inquired of John McCosker (Steinhardt Aquarium; San Francisco) on the aquarium's record of longevity with their frogfishes. His response:
"I do recall that specimens of Antennariius avalonis and A. sanguineus from Baja lived several years in the Aquarium, and it stands to reason ââ"šÂ¬Ã¢â‚¬Å“ once they became established in the collection they were fed every day and received appropriate medication if that ever became necessary. And of course we didnââ"šÂ¬Ã¢"žÂ¢t put them in displays that had potential predators. So, if well kept, itââ"šÂ¬Ã¢"žÂ¢s probably safe to say that they could probably live longer in an aquarium than in the wild. But I donââ"šÂ¬Ã¢"žÂ¢t know if those data exist."
I strive for reef-quality water, massive skimming and regular waterchanges, temps around 75Ã"šÃ‚º-78Ã"šÃ‚ºF (~23Ã"šÃ‚º-26Ã"šÃ‚ºC), a high quality and varied marine diet, strict quarantine and dip protocol, frogfish-only systems, and lots of observation.
