Ya... my riccia can grow in my high temp tank, at 30-32c day time, 28-30c nite time.... However, my xmas moss die off due to that..... Other local species is doing ok..... glosso not doing so well, instead growing horrizontally, they grow kind of tall....maybe due to lighting.
I am not so keen to invest in a DC fan as my adge of my tank is full of stuffs:a hang-on filter and 2 clip on FL lights.... So, my edge at the bank is kind of fully occupied...
Will try to master the riccia first, before switch to other expert type....hopefully.
