My zoas are being EATEN!!

[Tusktusktuskfish]

I have an Australian tuskfish, lawnmower blenny, diamond goby, black damsel, and a six line wrasse.

One of these is eating my zoas and palythoas.

Like almost all of them in 1-2 nights (roughly 10-15)

Who done it!?

100g tank
2ppm nitrate
0ppm nitrite
0ppm ammonia
1.025 salinity

Anyone?

How often do you feed?

I have found algae eaters and grazers to be more likely to go after corals, so the blenny is my main suspect.

The tuskfish is my next suspect bevause they are curious and can do damage, but their teeth are more equipped for going after motile inverts, not sessile ones.

Any starfish or urchins in the tank?

None of those. It was probably nudibranches.

Possibly, but sixlines are pretty good at controlling them. Also losing that many that quickly is unusual for nudis.

 

[Tusktusktuskfish]

I feed 2 cubes of brine every day, no other occupants in the tank other than a couple hermits and a Halloween crab.

 

[Tusktusktuskfish]

No visible nudibranchs in the tank, an Acan also was torn off it's frag plug and missing. It's pretty barren in the tank, only the zoas, fish, duncan, flower pot and Xenia. They are all small frags, the zoas were added about 6days ago. All appeared to be in good shape but I may have skipped a single day of feeding. They disappeared over night

Up until you said an acan was ripped off I was calling out asternia starfish. But if the acan was ripped off I agree with @eatbreakfast that it was either the Lawnmower blenny being to aggressive eating algae in between the polyps or the Tusk.
