Quick question about fragments and discs

I have two coral fragments on fragment discs, am I supposed to take them off the discs or not ?

you can see the two frags on the left and middle there

 

it would be better to leave them on. Less stress less mess

 

OK cool thanks, and is the placement right ? or should I place them on LR ?

 

I would just leave them on, they will grow over them in time. As far as placement, what are they?

 

We need the name of the corals, tank depth, and lighting to determine where they should be placed in the tank

 

hmm, I'll look for the receipt since I forgot the name of them lol (not so good with Latin anymore)
As for the depth and lighting, it's just a "stock" Red Sea Max 250, I'll get the info ASAP

 

light is 6 x 39W (234w) T5, 3 of them 10,000K (117W) and 3 of them are actinic (117W)
dimensions are 38" long x 21" wide x 26.2" high

 

here are the close up pics of the corals, not sure what they are, the receipt only says "assorted fragments"
