The white is just temporary like Jer mentioned. Jer is spot on with his reasoning for the whitish coloration as far as i'm concerned. I wish he would stay permanantly whitish looking!!..The loach is around 11inch, L25 is around a foot I would say & the L600 prob goes around 14inchHoly crap.....how big is that 'white' clown loach? Oh yea, how big are the plecos too?
