I would have to say clowns probably saved both my nems, since it was b4 this site for me and I had no clue how to care for them.
LFS said they were filter feeders, so for first year and a half I never spot fed them.
The sebae had a pair of clarki's(I had no idea of pairs) in it at LFS, but I only had enough $$ for the sebae and one clark.
After fishing one clarki, and then going for nem, the other clark swam into nems mouth.
OH well the guy said, goodbye to that clown.
I scrambled home and got nem in tank fast as I could, and couldn't believe the nem released the other clark!
It was badly tattered(started to be digested) but alive.
So I got a free clown, and now had a pair that took great care of my nems, always spot feeding them for me b4 eating for themselves.
Too bad as the clarks matured(probably spawning) they became evil to all fish and I had to ditch them.
But yes, I owe credit to those clarks for the first year and a half for sure.
