Torch white tissue recession.

[WereAllNegan]

I've had these two torch corals for about 6 months now and I noticed that the white tissue around the base of the head has started to receed upward.
Both torches extend fully and seem very happy. They've also colored up since I've had them but when I saw this It worried me.

The first video is with the lights on when I first got them.

The second video is with the lights off, thus the reason why they're not fully extended. You can tell the white tissue has receded since I got them.


On a side note:
I haven't read Nitrates or Phosphates since cycling the tank a year ago. I've fed mysys, reef roids, reef chilli, Amino acids and still read Zero. Hanna

Can’t see videos but likely inadequate light or too much water flow
Other causes are high nitrate/phosphate or low calcium/alk

You think it could be too much light?

Its unfortunate you can't see the videos. The flow in that tank is minimal.

From my experience as euphyllia grow and split its normal for the tissue to recede upwards a bit. If it is patchy or receding rapidly I’d be worried but both my hammer and green torch have recede like you’re saying and have split multiple times.

Thats good to know. They seem to be very happy so hopefully it's a good sign. How old is your tank? Are the videos I posted still not visible?

Take the light down (at least white light intensity) and see if it gets better
Any recent tests on pO4 or NO3?

My current tank is a year old and like I said every euphyllia I’ve ever owned has done that. I had a hammer for several years that went from 1 to about 30 heads, all were healthy and the tissue was like that on each head. Separated.

I'm going to test both and let you know ASAP. Heres what my schedule and light intensity looks like.

So I checked Nitrates and Phosphates. Zero on both. No matter how much I feed in this tank I can never read phos or nitrates. Even with out having algae. I'm so confused man

Sounds like false readings
What test kits are you using ? If API, you may be getting false readings
Have a trusted LFS that does not use api kits test your water for you and see what results they come up with.

So I'm using Hanna testers. Went down to SD corals in California and they confirmed zero on Nitrates as well as Phosphates. Up until 2 days ago I had coral only in that tank since its a pico but I got a tail spot blenny to see if that raises my nitrates and Phos. Hopefully thats the key

The skeleton isn't white. With a green base like that, looks like normal growth. Flow from the video on the torch looks fine as well.

Someone who is highly experienced with euphyllia.

I could be wrong.

 

[WereAllNegan]

Hello again! Just to update you on the situation, after getting the blenny my nitrates and phosphates finally went up and are detectable.

Unfortunately though, the tissue on both torches is still receeding. Both fully extend and seem happy though.

My light period is pretty conservative but I don't think that's it. I run the following.

1 hr ramp up
6 hours of full spectrum
Then a 5 hour ramp down only blues
Totaling 12 hours but with only 6 hours of full spectrum.

My current parameters are:
Alk 8.2
Phos .003
Nitrates .025
Salinity 1.025

Am I missing something? I really hope I don't loose them.

Have you made sure you don't have any euphyllia eating worms? I could not figure out what was causing a similar response in my torches and hammers until I learned (sadly much too late) that I had acquired the worms somehow.

 

[vetteguy53081]

Likely stress and often due to too much light and/or water flow.
Always dip to avoid flatworms and other pests. If no flatworms, confirm NO eggs which are VERY tiny

Any more updates to share? My torches look a lot like this too.

 

[Reef Devils]

Any updates? I have a similar issue.

Mind if I jump in here when you say in adequate light, would that be too much or too little???? I have some torch squirrels as well. I’m just trying to educate myself here.
