I got a ricordea from someone but it isn't mounted. I tried super glue-ended up floating away. Tore up my whole tank looking for it. Then, I tried the gel super glue. Ended up floating away again! ARRRRGH. Right now it is floating in a custard cup suspended at the top of my tank by a fish net. Someone help me please! What else can I do? If it floats away again, good luck buddy!
