Id say all of those plants had just come in, the glosso looked perfect when i bought it, other plants in the shop yesterday were suffering as well but none as bad as the glosso, the glosso was basically brown mush dead, other plants were doing ok but you could see that within another few days they would probably also be beyond redemption, but this is a common problem with plants in lfs, when they get them in they look great, come back in a week and they look ragged because of lack of light mainly, although they do use a decent amount of light on the tanks in there it still isnt enough, but i will say that its a lot better than most lfs that i have been to, i didnt buy anything i will wait for the next shipment, i will probably go back next friday or something like that and hope they have new plants in.
The Aqua Ones are only small tanks, some were nano tanks others a bit bigger, none bigger than maybe 15 gallons, but they look great IMO i think i will definatly buy one.
Ive been to the shop in the blanchardstown complex....absolutely no plants last time i was there.
Make sure the endcaps are waterproof if you dont have glass covers over the tank, you get big condensation buildups when the lights are off (as im sure you allready have discovered)
