What is this white spot on my tort?

[degibson84]

This piece as well as a frag of miyagi tort have these white spots near the bases. Both frags were fine last night. When I came home today I noticed these spots. Are they bite marks? The only new additions are a bicolor blenny and melanurus wrasse. I have never seen any tank inhabitants nip corals.


NO3 0.00 api
PO4 0.00 Hanna checker
Calcium 440-460 API
Alk 7.3 dkh salifert

These numbers have stayed prett stabile even though I have started feeding heavier to try and get some detectable no3 and po4

Also I have a yellow tort, purple stag and a pearlberry that all look completely fine

 

[degibson84]

Any ideas?

Maybe coincidence, but shortly after adding a Vrolik's Wrasse (basically the same wrasse) I found bite marks on a number of my SPS. After watching for a while I caught him nipping at the corals, but since they have a spotless reputation I assumed that he was eating something off the coral and the marks were "collateral damage" as I do have red planaria in the tank. Sure enough after a couple of weeks he stopped picking and the marks healed up. I still see him checking the corals over regularly but he never seems to find anything to bite.

I started thinking it was either the melanurus, coris or bicolor blenny. The coris has been in for a few weeks and I know both are known to pick at pests that can bother sps. I hope that is all it is and they heal up after a while. I dip everything and have only seen red planaria on my giant bubble coral. Never have I seen them on the sps corals. But since adding both wrasses over the last few months I have seen a decrease on the bubble.

Do you have crabs? or pygmy angelfish? looks like the start of STN

Only hermits and no angels.

 

[degibson84]

It's the bicolor blenny. Just caught him gnawing on the miyagi tort

 

[trueblackpercula]

Yup they are good for that

 

[degibson84]

If I move the two frags he is screwing with to the other side of the tank do you think they will be safe? He doesn't seem to bother the acros on that side.

 

[trueblackpercula]

Moving them will not solve the problem he or she will just look for them.
Your only option is to rethink about it you really like the fish or the Sps. One will have to got our choice.

 

[degibson84]

Why is it only the two he is going after? I thought maybe it was because they are the two closest to his "home"

 

[trueblackpercula]

Ok try it

 

[degibson84]

Now you have me thinking if I move them he will look for them and also try out my other frags that are doing amazing

 

[trueblackpercula]

you got it
