Black sailfin blenny eating sps

[Jcar]

I have a black sailfin blenny that likes to take bites out of some of the sps corals. He strips Clean a bird's nest and breaks off the tips on another random acro whenever they are starting to look good and putting on noticeable growth. They've recovered from it twice already I'm trying to stop it from happening again . Anything I can do about this guy without getting rid of him? He's a cool fish but limits the sps I can put in his tank.

Blennies eat coral... only safe one that I can think of is Midas. Gonna have to get rid of it or live with it. Sorry...

Just got rid of my bicolor blend yesterday. I caught his eating some of my acro's. Time will tell if they will recover.

I like him a lot he works pretty hard at getting rid of algae. Not sure what to do about it, I definitely can't put anything expensive in the tank but I don't want to get rid of him either

Kind of a broad statement? Kind of like all dwarf angels nip corals. Yet we know of many that never touch them.

In 20+ years of owning starry blennies, I have never seen a single one touch corals. Only experience with blennies I have. Love the looks of the starry, so it's the only one I've ever owned.

If it's currently eating coral, it probably will never stop. Either get rid of the blenny, get rid of corals, or live with it eating corals. Only options there really is

All dwarf angels have eaten coral. If you have one that doesn't then you are fortunate, but let's don't pretend that since your starry has not done it yet that many others have not. Midas is the only blenny that I know of that I have not heard too many people post about. They are risky. Period. They are especially risky with corals with tasty looking polyps.

I've never had a blenny that didn't nip corals, and I've tried many over the last thirty something years. My last lawnmower liked taking mouthfuls of Battlecoral polyps and spitting them out like colorful neon confetti. I currently have an ORA Molly Miller that hasn't bothered anything... yet. You think I'd have learned by now.

My tailspot got the blame for killing a few of my frags b/c they suddenly started to look poor, and then he was observed nipping at them each. However, a salinity issue was later discovered, so I'm still not sure if he caused the frags to die w/his nipping, or if he was nipping at dead/dying tissue and algae on them. If it was the latter, I still feel like his nipping ensured they couldn't recover.

RN all corals in my tank are doing well and I haven't seen him nipping at any.

Not sure what is happening but usually once every couple of months, I wake up to new branch growth (montis and acros) snapped hanging on by some tissue. Makes me extremely angry after a couple months of awesome growth just to have something randomly snap it off. I blame it on the 5 chromis that always fight at night. But never caught the culprit. Sometimes big tangs zip fast brush against a hammer coral just to watch 3 polyps explode off. I usually have a bunch tiny frags and usually they grow back into big frags in a few months, but this is still a big point frustration for me. Come to think of it sometimes I notice the broken branches after feeding. Like a tank full of pirhanas going crazy.
