Walt Disney acro not colouring

[Teeho12]

Hi,

I have had this Walt Disney sitting in my tank for about a year now. It's encrusting and has good polyp extension, but lacks colour. It's sitting at around 500 par.

Salinity 35 ppt
Nitrates 7.2 ppm
Phos 0.06 ppm
Alk 7.5 Dkh
Calcium 480 ppm
Magnesium 1440 ppm

Trition ICP all checks out.

How long have you had it?
Flow it is getting?
How does everything else look in your tank?

I have had it for about 12 months now.
Indirect flow I have 4 mp40 on a 4 foot tank.
Everything looks pretty average as well.

same for me, 1 year, no growth 600 par, all other acros growing like crazy

It is possible you don’t have a real WD. It is also possible that it will just take more time for the WD to grow and color up as your tank further matures. Being a coral detective is one of the fun parts of keeping SPS!

Plus there are "walt disney"....and "big r walt disney". No idea if they both are supposed to be the same

That does not look lile a WD to me. Polyps are not right.
As a note I have an eraser nub of a WD in my current system. It has not grown at all in a year, why, have no idea. I just moved it to my halide growout system and will see what happens.
Old 80 WD.

Beautiful colony and agree that it does not look like a traditional Disney.

It may not change into typical colors until it starts to branch out into a colony. Many times the frags are a different color than the colonies they come from as well. Mine is very slow growing and only 4” across after six years. The colors come and go, with the default being green with yellow polyps when not in peak condition. All I can suggest is elevated nitrate (I run in the 20’s) with a lot of flow and a ton of patience.

Here’s my nub w higher nitrates 40-60

Hi, usually it should color up when everything is stable, at least has some yellow/orange on it. Mine got lots of purple, probably bc my light is too close to the water in my 25gal.

In my short experience, Disney's are super slow growers. I got one in December last year. In February I decided to cut the plug it was on and broke it into 4 pieces. (DUH!). One main piece and three tiny ones. I glued the main to the rock and the three pieces to a plug.

After about 3 1/2 months, here is where all the pieces are today. My NO3 sits at around 20 and PO4 about .20. My dKH sits around 8.5. PAR on these is around 500 most of the day.

When they are nubs, it may take a long time to grow, but once they get to certain size the growth rate will increase exponentially.

This is what it looks like when I first got it

That looks like a Disney structurally for sure. I guess it just hasn't branched out yet. I have some slow corals that grow like weeds and fast corals that grow super slow. I guess some (regardless of species) just take their time to break out.

You're good then...looks legit to me.
