Great mini scape displays at Bangkok this weekend (ACT Aquascape Contest - ACTC 2019 by Aquascaper Club of Thailand ) at Atlantis JJmall (lvl2)
These tanks measure 45x30x30cm yet contain an incredible amount of detail. The theme of the competition had a focus on glossostigma elatinoides as a campaign against the fake "carpeting glosso/HC seeds" read more on the carpet seed scam here https://www.reddit.com/r/PlantedTank/comments/94nc5p/aquarists_beware_the_glossocarpet_seed_scam/. Thailand has an avid community of aquascapers who are especially apt at maneuvering small spaces. The usage of small plants and mosses aid the sense of scale. Plants used include (Glossostigma, Eleocharis species, Hygrophila pinnatifida, Rotala mexicana goias, various mosses, Rotala wallichi/vietnam/rotundifolia for backgrounds, Hydrocotyle tripartita, Hemianthus glomeratus, Ludwigia brevipes, Mini bolbitis species, Monte carlo)
Different leaf textures are blended together to give a sense of natural inter-growth. In most aquascapes there is an effective usage of shadows to increase the sense of dimensionality of the aquascape. Most scapes present also had a nice touch of color. One downside of smaller tanks is that it is hard to give a sense of open space - most aquascapers will attempt to maximize the space used for hardscape and plants. However, note that for every tank there is at least one distant horizon point visible as the backwall of the aquarium, this coupled with the steep slope of the substrate (each horizon at rear is at least halfway the height of the tank) gives a good sense of depth to the aquascapes.
Generally the tanks ran on low nitrogen fertilization regimes, which caused many naturally larger species (hygrophila pinnatifida & rotala rotundifolia) to grow dwarf/smaller forms and exhibit characteristic low N redness.
