Interstellar Mushroom need different care?

[FreeEnergyReefer]

I have a 75g mixed reef every coral is flourishing except my baby interstellar mushroom. I have it placed with my other mushrooms in a low flow low light section of the tank and it hasn't grown in the 6months I've had it. Is it like my yumas does it need more light? What am I not providing for this guy? PAR on the section he's in is 63 for 8hrs, 83 for 3 hrs. Also i have noticed twice he has spit a lil bit of guts or something white out at night and when the lights come on he sucks them back in immediately. Parameters are: Alk-9.3, Calcium-406,Phosphate-0,Nitrate-20,Salinity-1.028,PH-7.8(working on getting this up,only been low for the past month)

I have a variety with purple "stars" under a range of light intensity (higher and lower than your readings) and it's proven to be a very slow grower. I'm pretty sure they are Actinodiscus spp (formerly Discoma) which in my experiences usually prefer lower light than Ricordia and Rhodactis.

Ok, thx. I had no idea they changed the genus classification,doesn't surprise me they do it all the time. Literally right beside the interstellar is a superman disco and he's tripled in size in 3months. This interstellar has proven to be more challenging than any of my acro's. Glad 2 hear the general consensus is that they are slow growers. Even though I'd love for him to grow the fastest. Anyone had any luck feeding them?

I thought discos grew fat. i thought of getting one. Actually I won a huge one on ebay for 40 bucks or something and local pick up then the guys tells me to just pay when we meet so he deletes the sale. I figured he just didint want to bay ebay fees but totally never answered me back after that! Scumbag! lol
