Emerged/hydroponic Plant Suggestions Please

I'm impressed.

I've used the "lucky bamboo" stuff, still in their little containers, for a bit of greenery on the land part of one of my midskipper tanks, and it has grown quite well.

Ooo, this is something I was thinking of doing too. Great idea.

I found a guide on how to acclimatise house plants for hydroponics, which is pretty much the same thing as you're doing. They also recommended a list of plants that can be kept this way. Note that some plants from the list might be poisonous if eaten (fish might graze on the roots I imagine).

The guide recommended that the plant is covered in plastic for 2-3 weeks after being put in the water to prevent excess water evaporation.

Here's the list of recommended plants:
Abutilon, Achimenes, Adenium, Aeschynantus speciosus, Afelandra squarrosa, Anturium x scherzerianum, Ardisia crenata, Argyranthemum, Callistephus chinesis, Rhododendron simsii, Catharanthus roseus, Begonia, Begonia scharffii, Browallia speciosa, Brunfelsia pauciflora, Bougainvillea glabra, Zantedeskia, Celosia argentea, Cyklamen persicum, Senecio cruentus - mieszańce, Mimosa, Campanula isophylla, Aechmea fasciata, Echeveria, Euryops chrysanthemoides, Eustoma grandiflorum, Exacum affine, Freesia, Gardenia jasminoides, Gerbera, Gloriosa rothschildana, Gmphrena, Hyacinthus orientalis, Hippeastrum vittatum, Hoya, Hydrangea macrophylla, Ixora coccinea, Iris reticulata, Justica carnea, Jasminum, Kalanchoe blossfeldiana, Kalanchoe pumila, Kalanchoe 'tessa', Calceolaria x herbeohybrida, Camelia japonica, Anigozanthos flavidus, Hibiskus rosa-sinensis, Clivia miniata, Crocus, Selenicereus grandiflorus, Curcuma, Leptospermum scoparium, Lilium longiflorum, Catharanthus roseus, Mammilaria zeilmanniana, Medinilla, Passiflora, Citrus mitis, Hypocyrta glabra, Narcissus, Nertera, Impatiens, Orbea variegata, Calathea crocata, Pelargonium grandiflorum, Peperomia caperata, Pentas lanceolata, Primula obconica, Solanum pseudocapiscum, Capsicum annuum, Puschkimia scilloides, Rehmania elata, Rosa, Saintpaulia, Sreptocarpus, Spathiphyllum, Smithiantha, Senecio grandifolius, Stephanotis floribunda, Cymbidium, Dendrobium, Odontoglossum, Cattleya, Miltonopsis, Phalenopsis, Phragmipedium, Pleione bulbocodioides, Paphiopedinum insigne, X vuylstekeara, Strelitzia reginae, Justicia brandegeeana, Syningia, Muscari armeniacum, Oxalis, Tulipa, Euphorbia milli, Euphorbia pulcherrima, Ipomoea, Dendrathema grandiflorum, Lithops.

Thanks @Dominika Wow that list have given me some reading to do. Do you still have a link to the site please?

I do, but it's in Polish,

The guide is here.

The list is here.

If anything's unclear in google translate, just let me know.

I imagine from the list that hyacinth would make a really attractive option... however I think they are seasonal. 

Just showed your first image to my wife and she loved it. You might have a copy cat in the making here @Andy The Minion 

An update on the planting, the experts at gardeners question time weren't able to suggest much - I guess they don't go too near hydroponics in their day to day dealings. Matt Biggs was the most helpful he suggested Aglaonema, Chinese Evergreens and a Philodendron but both are very similar to the current plants.
One of the dealers who was giving a talk and then a Q&A afterwards took a different tack and said that the conditions the tank provide will suit virtually any plants needs and just try anything that grabs my fancy, so I have my eyes peeled for likely victims.
I checked the garden and the chickens have found all the strawberries so I added a dwarf Crocosmia bulb with just the roots dangling in the water and the bulb wrapped in some foam to keep the light off it (no idea if it's needed, just seemed a good idea) I also have a nice variegated spider plant that is flinging off loads of flower spikes and spiderlings so I will try splitting that at some point.
I have also added a few leaves off a larger Epipremnum that just happened to be in the hotel we stayed in (I did ask first) to the big tank along with a runner that was growing out of a ground cover evergreen plant with medium sized deep blue flowers in the car park at work and a section of an outdoor climber with large red/white five sided trumpet flowers we have in a pot (no clue what either are) All three appear to like the conditions and are noticeaby growing after just a week. It is early days and I'm not sure if it's a direct effect yet but the water test this week showed a noticeable reduction in the weekly NO3 production. This tank is fed heavily as there are a lot of growing Blue Acara in it and I have been doing big twice weekly changes to keep the NO3 below 40ppm. Today's reading was 31.5ppm without a mid week change, so if it stays this way the plants have almost halved the Nitrate production.
None of the plant in the big tank are visible as they are inside the hood and I'm resisting the temptation to start modifying the Perspex lid, let's see if I can keep to this when they are all around the tank top.

If anybody has an interest in gardening or even just nature I can thoroughly recommend the BBC GQT garden party, it's a fantastic day out and this was my 3 year. Ness is a good location and because it's attached to Liverpool University, they have professors lurking around and giving talks on the experiments that are running there. One also took us pond dipping, the pond was chocked full of weed and absolutely full of life, I got a macro photo of a Great pond snail egg sac which came out very well. I wish I had kept it as I'm sure they would have done well in the sump living off the algae in the scrubber section.
I will post two pics after I post this as with this much waffle I don't want to risk the photos crashing the post.

Just a quick update on the plants, they are all putting on lots of growth and the weekly NO3 production is sitting at about 8ppm/week with the same fairly heavy stocking levels so they are doing a good job. A recent addition to the plant spicies found its way in.... Willow the kitten has decided this is an ideal location to hang out. A bit too much temptation for there not to have been some ad hock feline pruning but I can live with that.

@Matt If The roots will be too noticeable then probably don't use Peace Lily but the structure of the leaves are probably the best looking of my species (tall broard, back right) and it should flower at some point. I have a couple of these in a sump and put them in a section of PVC to support them, this would certainly hide the roots and the pipe might be less noticeable depending on the colour. The Epipremnum, long trailing variegated one that is curling around the cat is the fastest growing and probably best suited to the enviroment, but it will need support. It could be trained to produce something easthetic I'm sure. There are several varieties of this plant and I also have a much larger leafed non-variegated one in my big tank. Just keep your eyes open for these in hotel/company receptions or shopping centre planted displays as they will grow from a short section with just a couple of leaves. The 'lucky bamboo' doesn't seem to be growing massive roots but it's not particularly impressive - maybe a clump of stems would though. But like I was told by the experts I asked - find a plant you like the look of and give it a try, providing it's not a cacti you take a shine to it will probably survive because it will have everything it needs to grow.
