Cryptocoryne beckettii
This Crypt beckettii is notoriously easy to keep. It has a unique bronze color to it.
it would make a nice contrast in your foreground or mid ground.
It is intentionally brown. This plant can handle low light conditions without a problem. Under higher light it will grow faster.
We recommend splitting up all Crypts about an inch or so.
I am a firm believer that Crypts like a good substrate. However many people have been able to grow them for years in just sand.
