Hey guys, I have had 3 clown loaches for about 2 weeks now. The smaller of the three has a really vivid black coloration along with the orange. However the other 2 are really quite grey where they should be black. They bicker all of the time, going nose to nose and chasing each other. I have read that they are fighting for "top spot". Is this correct? and is there any way I can stop this behaviour, so as they will colour up like their buddy?

Most likely.

Probably not. It's a relatively common behavior (both the fighting and the color changes) accord to this article: http://www.loaches.com/articles/clow...ing-variations

Well folks, I have discovered that my clowns like to change colour when I feed the tank. Also this morning I gave them some cucumber and all three of them were clicking away like mad. I thought the tank was cracking or something as I had never heard it before

Them changing color is normal. Too a show of dominance and aggression. Here is a link you may find helpful. It's called graying out.
