For sale is a clump of beautiful Dwarf helzine/Hemianthus callitrichoides ‘Cuba’ or often abbreviated as HC (see photos below, read an article by Tropica here). This plant is quite difficult to get hold of in the UK unless order online or through special order by LFS. I bought it from Tropica through my LFS. It is one of the smallest aquatic plants and it is commonly used to create foreground carpet plant often featured in Takashi Amano’s nature aquarium tanks. In highlight CO2 injected tank, they will create oxygen bubbles or pearling (see photos below). Because this plant is very buoyant, initial planting is a real challenge! I find it easier to partially bury them into the substrate and wait until roots take a firm hold. Once established, it will gradually craw along the substrate and form a beautiful carpet. It can also be grown floating but fronds will tend to grow downwards in search for substrate to hold on to. My Tiger and Crystal Red (CRS) shrimps just love to pick on debris trapped on them! It also provides hiding places for new born shrimplets!
See my tank setup here and more photos here with very healthy fish and shrimps (all disease-free!!) and I do not add any medications to my tank but I do dose plant fertilizers (mostly from Seachem). It is advisable to rinse and inspect for snails before putting them into your aquarium. |
