Right so bottom end is it's not what I ordered, they are still in store at moment and noticed the k1 myself however I was showed that they have a massive trickle tower for each tank so think it's in addition or maybe to show it has filtration to newbies, the media wasn't really moving much either so maybe it's for seeded media but again not my tank so can't say for sure. Might ask when I go back in a few days.
The shop is quarantining them for a couple weeks as I requested when I ordered so if I feel it's not right might turn them away.
Discus are currently 2.5 inches - 3 inches. Think out of all suggestions it looks most like stendker alenquer as it is white - very light blue patterning on edges. However the black lines look more like stress lines to me which would make sense given the fact they only just arrived when picture was took.
If it is low grade red melon then I am annoyed by price as I paid £35 each but it really doesn't look like it.
Don't get me wrong though they do look nice and even though they were newly moved swam straight up to me, there eyes looks good but also noticed a few of them have unusual sloping of head.
Going to go through another list tonight to see if I can match it
