Try a different plant...Here in my state particularly(kerala,India).The govt. are trying to get rid of this plant as it multiplies fast and leads to overgrowth and thus covering the surface and cutting of the oxygen supply.This affects aquatic life a lot.
I live in a waterfront appartment so this hyacinth are there in plenty(depending on tide) so some of them are quite large with a diameter of 3 feet+.
They're leaves grow and become pretty huge,they have long roots and this weed is also suprisingly heavy.It flowers as well,the flowers look really good cant deny that.
Overall its going to require a lot of maintemance.So kepping it in an aro tank especially when aro's are top dwellers Is a BIG NO.
This is just my opinion there could be people who could disagree
