Hey Reefers,

I've never had a frogspawn before (I know, shocking). Is it normal for them to be this inflated/translucent? It doesn't look like this all the time but usually for most of the day.

I have many other lps (and sps) that are doing great, including a duncan and torch in similar light and flow, so I would be surprised if it was the lighting or something. I have an ATI Sunpower 9 inches off the water (18" depth and it's on the bottom)

Params:

Salinity: 35ppt/1.026 S.G.
Temp: 78
pH: 8.1
Calcium: 440ppm
Alkalinity: 9 dkH
Magnesium: 1380 ppm
Nitrate: 4 ppm
Phosphate: .02 ppm

It feeds happily on mysis once a week and is growing. My feeling is that it is completely healthy and this is normal, but not sure.

Thoughts?

Thanks!

look's MILDLY bleached to me. could just be the blue's. Mine is a much deeper green but established now, but still somewhat translucent. more opaque tho, but still somewhat translucent.

Agreed; looks a tad bit bleached out.

I dont think its "bleached" in the traditional sense (evacuation of some zooxanthellae) because that would be consistent for more than a day, probably a lot longer. It's not translucent or pale when it is less inflated and zooxanthellae do not return and go in that fashion. The color is a direct result of the inflation. Here is a pic of it less inflated:

and even less inflated:

All 3 "stages" are seen on a daily basis. Obviously the lighting is different however you get the idea as far as the different stages of translucency. The different lighting only makes it look less or more fluorescent, not less or more translucent.

It is however, less inflated and extended at night and early morning than during the day.

Any other ideas, anyone? Is it normal?

I guess dose some phytoplankton / zooplankton & vitamin -amino acid supplements on a daily basis. Use any good commercially available products like seachem etc. The coloration of any coral is result of organic sunscreens which they produce to shield zooxanthellae to avoid over exposure. Also only mysis might not be adequate. Try some varieties in coral foods. This shall work. Frankly I have seen in many cases lps suffer in similar fashion in highly skimmed & low nutrient systems.

yeah, it looks normal to me. Same with it deflating, mine do it too.

This is how my buddies looks in his tank. Mine from tge same colony however has very plump tenticles, easily matching the size of a pencil when fully inflated and is very hard to see thru.

His tank has low inorganic nutrients but detritus is not very controlled. . My tank has low inorganic AND low detritus accumulation. I feed about 2x as much as him as well. The same is true for all euyphilla we have, 2x frogspawns and a hammerhead each, and all from the same colony.

Your pic looks similar to one I have. In my case it is always a bit translucent. The coral I have went from 1 head to 4 seems happy to me. I wouldn't worry time will tell.

Yea I believe it is normal and possibly light related (inflating to gain surface area for more light or inflating to increase translucency and reduce light absorption).

It could also be flow related, my Duncan over inflates and turns a fleshy color in low flow, but looks fantastic with proper color in medium flow, and compact with exaggerated colors in high flow.

Any issue with "bleaching" and zooxanthellae and all that is not something that goes back and forth throughout the course of the day.

I also dont believe it has anything to do with feeding because a) I feed it once a week and b) frogspawn don't even require feeding.
