I prefere yo-yos, dojos, and horsehead loach. yoyos are a cheap, better looking botia, dojos: cheap, active, can live in almost any fw tank(water wise), can live quite a while after it jumps out of tanks (unless you have cats), and I had a 5" horsehead loach that took small gravel into its mouth, tumbled it, and cleaned it thouroghly, then deposited it out its gills. never liked the look or price of clowns (and khulis). I understand clowns can get well over a foot wich caches my interest, and they are intelligent. i'll give em a shot
