It's ok. Thank you for the reply.
I'm activly trying to catch them to
exchange them.
I bought them to control my bubble
algea problem (tap water probably). Since
they are not doing it, I'm going to remove
them. Just to be safe. So far though, they
have left my coral alone.
Again, thank you. Have a good day.

Hey Scott. I was more along the lines of other species besides Emeralds.
Some species are freakin ugly little hairy bastards that go after corals. I
am not sure about the different Emeralds. From what I have gathered,
Emeralds are Emeralds. It is just that some have appetites for polyps and
some don't. It is a gamble...
I would say, if the ones you added are not eating polyps, coral or algae,
they are finding food elsewhere. They are opportunistic scavengers
(sometimes predators) and will eat whatever is easiest to get their claws
on. Maybe consider not feeding the tank for a few days, then only feed very
lightly. Make sure not food hits the rocks or sand and see if that changes
their appetite towards the bubble alage....
Just a thought, sorry I could not help with your question...

Shane,
Something you just said hit me about Emeralds.
You mentioned removing the hairy ones. When you
said that, did you mean the Emeralds with lots
of hair on their legs?
If so, here is some info. I have had great success
with Emeralds in the past for bubble algae control.
However, the latest 2 that I've added have done
Jack - nothing, nodda, etc. They refuse to eat it.
One thing though, the legs are really hairy. It's
an Emerald for sure, just that I don't remember my
other Emeralds having so much hair on their body.
Are there Emeralds with and without hair?
Just thought I'd ask.
Have a good one.

My advice, next time, no matter how tired you are, if there is a
crab that
is eating your coral, get it out of there (if you can). You may not
get the
opportunity to do it again. As for crabs in a reef, other than the
crabs
that live in coral (and don't eat it) I don't like them. I have
heard
Emerald Crabs work nicely, but I have also heard of them eating
polyps and
such. They are good scavengers though, so maybe concentrate on
removing the
hairy ones and leaving the others. See how that works...
FWIW

Dear list,
Two weeks ago I removed a 2cm hairy crab from my tank
because I saw
him
striped out my bird nest coral within 3-4 days. Actually I
have seen
him
amongst the coral since I have it (approx 2 mothns). But one
day I
found my
bird nest striped out and the crab had moved to another bird
nest
frag and
also he started to eat it. So now I already have it removed.
Last night I found another hairy crab (1 cm)in my other
tank. And he
also
ate my red pipe coral. I was too sleepy to remove it, so I
just
drived him
away.
So do you think crab is a no-no to a reef tank? What about
other
species?
Because I have anothers (w/o hair) who had grown up to 4cm
and 2cm
but I
never saw them do any damage to my reeftank.
TIA,
Jim.
