spotted mandarin and Six line Wrasse

I got a small six line wrasse about a week ago and its harassing and attacking my spotted mandarin which has been in the tank for 3-4 months.

Is this normal behavior?

I have never seen any fish even acknowledge the mandarin before.
 
Unusual behaviour indeed. Mandarins generally don't get bothered by anything other than same sex mandarins.
However, 6 lines can be very aggressive and territorial but am still surprised about it harassing a mandarin.
IMO you should remove the 6 line if it continues.
 
6-line wrasses are notorious for killing mandarins. Sometimes they just poke their eyes out. You need to remove one of them asap :(

OK - didn't know that (you learn something new every day:)). How are mystery wrasses with mandarins.
 
I don't know how they are with other wrasses per se. Mystery wrasses are gorgeous - beyond that I don't know

Since the 6-line is capable of depleting the mandarin's pods, it's not a good choice with a mandarin anyway. I'd avoid any pod eating wrasse with a mandarin. Fairy wrasses should be ok

Now I have to find a way to catch the six line.

Sometimes 6-lines can be easy to catch:

If you can find how which rock he sleeps in at night.
And that rock can be removed
Awhile after lights out - switch them back on
Quickly remove the rock to a rubbermaid container.*
The 6-line should wiggle out of his hole.

*Might be kinder to have tank water in it ;)

Good luck!
 
I assumed in a 210 gallon with a large fuge the pod population wouldnt be a huge issues, plus my mandarin is eating frozen mysis.

It might not be if you have enough rock, I'd nevertheless be inclined to think it wouldn't be wise. I could be wrong, I've never tried it. Did someone advise you it was ok?

I have 350lbs of rock my LFS said it would be okay but I should know better to listen and do my research I was caught up in the moment.
 
Well I learned alot today which is always good. Once I catch that six line its going back to the lfs. thanks everyone for the great info.

Believe me all of us have made plenty of mistakes in this hobby. And all of us are still learning.

I only asked if someone told you it was ok because maybe they knew more about it than I. But since it was LFS advice...well, I'll stick with my own opinion :lol:

Good luck catching your fishy :)
 
any advice from you guys on six line wrasses? My tank has recently been overrun by pods and I ordered a sixline wrase to help keep it under control. It will be in an aggressive tank with large (8"-10" angels) and tangs. Will it do OK and eat the pods?
 
Pods are beneficial to your tank. Not sure why you'd want to get rid of them. But yes, it will eat the pods.

You mentioned extremely large aggressive fish... regarding the wrasse addition -- if some of your fish are small enough to fit in the mouth of some of your other fish, in my experience, that is the plan. ;)
 
the pods look like thousands of little speck-like insects running around my glass. My oversized wet/dry and H&S skimmer seem to have things under control. My big boy angels are lovers, not fighters. they won't eat a wrasse but they problaby will let him know his place in the pecking order. the pods are freaking me out. they look like parasites.
 
In my experience, it's better not to react to tank events if it's not necessary. If you're having a pod bloom in my opinion, it's better to allow the tank to come back to equilibrium on it's own.

That's just my style of husbandry -- to each his own. I probably should try to be less bossy
:D
 
You are probably right. However what will the equilibrium be with large fish that poop non-stop? There may be a never ending food supply for these guys.

Now that we are on the subject, what exactly comes out of the so-called-benificial critters that eat the poop? It can't be cotton candy.
 
Yes it's cotton candy! :lol:

I know what they eat >> detritus, bacteria and microalgae. I suppose they poop their own itty bitty fecal pellets. What exactly happens to those?? I dunno, you've got me there.

What I assume happens with a copepod bloom is the pods are outgrowing their natural predators, bigger pods, for awhile. You'd expect that to fall back into balance.

But I can't even imagine the bioload with such huge fish like you have. My idea of a nice aquarium ecosystem may simply not apply to your situation.
