my Zoa tentacles are growing long?

[UnderCoverDork]

It seems that my zoanthid tentacles are getting a lot longer after putting a new frag in my tank.

They are growing super fast, but i was wondering what was causing them to grow out there tentacles.

Thanks

I think sometimes due to flow in the tank... sometimes stronger flow enduces that ?

i do have strong flow..820gph in my 20g..its mostly sps though

thanks

What's your salinity at?
I had the same problem and discovered after many headaches that my refractometer was not calibrated properly... though I calibrated it according to the manufacturers directions.
My salinity was low, 1.022 or thereabouts, once raised the skirts became normal again.

YMMV

Hummmmm...that is a good question..

i think it is at 1.025, but my refractometer might not be reading right!

Thanks smp

My salinity is good, and only 1 type of zoa ( reverse Gorilla nips ) have LONG skirts , but that colony is higher up where flow is stronger.. which explains the longer skirt and waving in the current

Thanks^

i think it might be the flow, but im going to double check my refractometer

Its because of flow. High flow will increase skirt length. Check out my rainbow palys with about 1300gph over them. I think it looks cool

Here are some of mine with about 40x turnover in the tank

they do kind of look cool..

Wow they look like different corals..

 

[madadi]

they do look so different. so if you move them to a low flow area they get short again and vice versa? will some zoos get longer then others in the same strong flow?

 

[lfduty]

you need to feed them more

 

[impur]

madadi - yes if you move them to less flow the skirts go back to normal. I do think some zoas are affected while others are not. Here is a pic, similar flow over the rainbow palys, ring of fire, and eye of rah but only the rainbows have long skirts

lfduty - it has nothing to do with food.

I have a ton of diffrent zoas. Most should have around the same amout of flow.
My mean greens, and rasberry fields and a few other all have short skirts. It is just my AOG's, BAm-Bams, and thoes grenish yellow ones tha are doing it.

Here are a few other, some iwth long skirts and some with short...most should have the same flow...
