ok guys...thanks...will try to change my water source...relocate them....and medium change...
by the way...may i ask something...how much is too much light for these guys...or have to see if the got sunburn first to know...??
and can they survive under artificial light...been planing to put them in a aquarium with partial sunlight + artificial light source (namely 1X55watt PL-L)...is this posible??
for my part....as long as they not dead is an achievement on its own...
