Yeah, relatively short lifespans as the longest was something like 4-5 years in the 20,000 coral reef at the Long Island Aquarium. One would expect them to easily live out their natural lifespan in such a setting, and possibly go past it, so if they can only make it that long there, it suggests that they're just one of those fish that doesn't last forever. That shouldn't be terribly surprising. Good luck with Kate's pair - I know she's had them for a little while too (i.e. she had them a year ago) so if they make it through the initial shipping stress, you may still only have a limited amount of time (so truly best of luck, someone needs to be #2).

I'm glad to hear you're still attacking the project Kathy! Good luck with your new pair.

The new pair appeared to do very well for me for several months, and then the female started to look a bit thin. I increased their feedings and they seemed to do well again, and then the female stopped eating and died a couple of days later. I don't think they ever spawned. I am disappointed and bummed out by this turn of events, and I've given the robust male to an expert aquarist to keep as a pet in his large system. The friend will return the male to me if I want to renew my efforts with a new female. I am on hold with the filefish right now, and will focus on other species for now.

Kathy, do you ever worm your fish? I had awful experiences trying to obtain a small harem of Pearly Jawfish for my reef tank. They would waste away and die despite significant feeding schedules. I found if I wormed the Jawfish with PraziPro while they were in quarantine (after they had been eating well for at least a week since PraziPro can cause temporary anorexia) I had much better success with them. Now, when I see a fish wasting away I will add PraziPro to the food as a top dressing much in the same way as Selcon or Garlic Extract, and I find this really helps. Just a thought...

That's a great idea, and I do suspect intestinal parasites. Next time I'll try that.

Kathy, I have had the same experience but have never found intestinal parasites. FWIW, I had several on display for 3 years and then lost 3 of them quick due to wasting. That said, I can't think of any reason to not de worm them.

Thanks Rich,
I'm going to wait on these for a while. I want to get some easier fish done first. I don't think I'm ready for filefish yet, given my setup and experience level. Not closing the door, though. Just on hold.

It's experiences like this that lead people to say there's a nutritional issue in their care. As an interesting side note, I recently stumbled across a Brightwell Aquatics product, AngeLixir, that's designed as a food soak for spongivorous fish like Angels, Butterflies and Moorish Idols. Who knows...maybe I should ask Chris to look deeper into replicating the SPS nutritional profile? Afterall, I had my best success long term when these fish were in reef tanks...maybe they grazed on something I was not aware of that helped sustain my fish. Still, they do seem to have a definite "ticking clock" in their lifespan...

Which of course is an idea that has little to support it (just like the worm idea - though I understand that you gotta try something). I would expect that if it was a nutritional issue I wouldn't have been able to keep them for 3 years on the same food before some of them started to waste.

Is there science behind the basic idea? Is there science showing that it is beneficial?

Mine showed no signs of wasting in my care. One jumped and I lost the other in a tank crash, both over a year in my care when they died. Neither showing any weight loss.
That said, I have a cat that is wasting and its just her reaction to advanced old age and the vicissitudes of her life. Given how short the lifespans seem to be for these fish, it doesn't seem unreasonable to me for people to have seen signs of old age already.
That said, I would certainly suspect parasites first and take some steps to try to get rid of them before giving up on the fish.
