I add some basic fertilizer to get these plant going, my intention is to get it use to the lowland heat and produce runners so that I can get new plants.
These plants are isolated in my Ornamental set so any addition of fertilizer or supplement is mainly only for this set.
I use simple Chicken manure fertilizer since I do not want any chemical base that could cause problem to those fishes. The fish use is not for consumption since this is an experiment and a trial to see whether I could succeed in getting these plant to grow in the low land.
I add about a tea spoon for each plants and will repeat on condition but I would estimate every 45 days. I am also constantly monitoring the fishes to see if there are any side effect on them.
