Zoas core is open but not the tentacles.

[Eniram]

Hey reefers out there.

Don't know why my zoas tentacles are not expanding as before, the core is open but not the sides.

Pls see picture to understand better. Did a 50% NSW change and still no effect, dosed iodide also nothing happened.

Pls advice.

did you shift it recently or sometime back?

and how long you have it and how old are your lights?

i agree with bro law on his questions. tell us about the lighting too.

Didn't shift them, bought these together with the rocks so its practically attached to the rocks. Had them for 5 mths already, it was opening up as per normal. Its been going on for a mth already.

Lights i'm using are 4 HO T5 for about 5 mths.

the previous owner did use MH for his tank so i don't know if this will effect the zoas? but if so the first 4 mths its been doing well opening as it should be.

for me, when these occurs. normally its because of lighting. Perhaps you should wait and see or simply spend the money on changing your light tubes.

sorry Eniram, I could only able to help you this much.

No worries law thanks so much for your help. Yea am thinking of upgrading to LEDS. DE Lightings are selling it but am waiting for the newer version where the fixtures comes with extentable legs

Pls call me jeremy.

Oh and whats the ideal time frame to change light tubes?

[LaW]

for T5, the europeans and the richy rich americans suggest to change T5 tubes every 6months or a year.

for us(most of us), the more conversative, changes about once every year.

MH bulbs about 9-12months as well.

depending on source of brandings for each individual as well.

so are you going to be richy rich?

LED, I believe its longer.

perhaps you should shift that colony up higher for a few weeks to see if lights are the cost. for me when I shift zoas down to lower level, their tentacles will be shorter and they open not as big as before. so play around with location.

it was nice sharing with you Jeremy

happy reefing
