i see... think i should be doing the right thing... am placing the "dead" ones together with the mature ones coupled with good water circulation... but my small 2ft tank is now full of rocks... and it would be like that for a few months...
probably re-scape before CNY...
Got a few pieces of dried ones from a friend... washed and placed in tank... but how long should I culture them before removing the older, smaller ones? Can any kind soul advice? Thanks!
