Well it's only happened twice, but both my purple fire fish have disappeared. They were doing fine, seemingly unbothered by other denizens, then they just vanished. I have a biocube with a lid, but the little access hatch is open for the automatic feeder. Could they have managed to aim for that opening (then a dog removes evidence)? They're not hiding in the back with the filters. The most aggressive thing in the tank is a pushy clownfish, but the timid clown goby doesn't seem to be bothered by him.

Pretty sure there is plenty of hiding spots. They both would hide nightly and seemed fine until they stopped showing up. Here’s a pic from the side. I’m fairly sure I have no secret predators in there… Coral banded shrimp, serpent star (plain black), too many BTAs (down to 4 from 6, they were taking over), a sizable bristle worm or two (not fire).

That is one of the fish I've tried many times over the last 20+ years. I don't think I've ever had one last over night for me. They go hide and I never see them again.

The serpent star getting hungry and going night fishing would be my bet.

Try either moving the serpent star out to another tank or feeding it directly right along with the fish and then try again.

they have a pretty wicked hunting style… If you google a little, you can probably find a video. IMO they only do it when they're hungry/starving… They would have no defense from a predator so I'm sure it's the last resort. keep them fed.

I have wondered about the Star and shrimp being the culprit, but the local LFS said that’s not likely. The Star is amazingly fast during feedings tho. I do feed a mysis shrimp cube weekly. The star and shrimp go crazy on that day.

It can be a little hard to believe if you've never seen them do it. their description is perfectly accurate though.

I would not say get rid of them, though. Just make sure he gets target fed along with the fish just about every day.

TLDR: I've lost 3 Firefish, a Clown Goby, and a juvenile Clownfish. Aggressive Clown and Serpent Star are gone.

My LFS (who also helps service the tank) said the large female Clownfish is very aggressive, which I certainly agree with. She said it looks like she's defending a clutch of eggs and was not at all suspicious of the Serpent Star. She said stress from the bullying could be causing the lower, more timid dwellers to starve. I upped feeding since water parameters are great, Spot fed the Star and added pellets for him to scavenge. I since lost the Clown Goby AND juvenile Clownfish.

I re-homed Mrs Bossy. The serpent star can be attributed to all, but the Clownfish seemed to not fit his profile. This week I got #3 Purple Firefish along with #2 Clown Goby, and the kiddo was quite fond of a Royal Gramma. The Firefish didn't last the night.

I'm 99% sure that the serpent star is hunting and becoming very good. The Gramma claimed a little cave under a rock overhang. This morning the Star was using his body to form a third wall to seemingly make it a trap. I zipped up to the LFS with Serpent Star in tow and came back with #4 Purple Firefish. I figure I can also attribute the Clownfish to him if he was "evicted" by Mrs Bossy and became more vulnerable.

If this Firefish doesn't make it, I think I'll be done with them. I'm not too suspicious of the CBS as it seems that the fish that have gone missing are far too large for him to overpower (several times his weight)... even if he had plenty of time getting a propper grip. And I really like him.

I plan to get some new clowns once these folks settle in. Leaning toward Frostbite and Midnight (complete opposites 😊).

In good news, my Kenya Coral is flourishing so well that it's almost too big. A second one popped up on a rock and is now big enough to be a centerpiece on its own!!

This is the answer. Nightime is not friendly in the reef.

The Firefish did not last the night. I spotted half his body. He’s small enough that the CBS could have caught him, but I don’t think I could see many of the others being solely his fault.

I’ve thought about getting cameras to document nighttime activities. I winner got effective that would be because there are so many hiding spots and such. Might be interesting anyway.

Were you able to find the body at all, or is he just gone?

Yep. The front 2/3 of him was in the back. The shrimp was nibbling on the other third.
I'd say it's either the shrimp or you have another hitchhiker in the tank that you don't know about. They can get pretty aggressive as they grow larger, and firefish are especially vulnerable since they usually find a crevice to sleep in at night.

Yeah the firefish seems like prime prey for a night hunter. He corners himself. Given the choice, I’d take the BCS over the fire fish tho. As long as others don’t go missing. Hopefully the main hunter was the serpent star.

I have seen stories of massive bobbit worms going undetected tho. Will have to continue on. Maybe find a cheaper source of fish too 😭
