Help : Clown loach vibrating

[ckk125]

hello all,

Is it common for a clown loach to vibrate?my 11 inch clown loach keeps on vibrating...tail and abdomen. Is it ok?

Apart from that, he seems to be doing quite well..

Thanks!

Yeah, that's weird. Almost looks like he's settling himself, but not quite... Got a sweeping powerhead? Maybe the current keeps disturbing him? It's not the usual quiver of an excited clown loach at feeding time....

I have seen mine do that when fighting with my other clown loaches. It could be a 'ritual' when sparing.

I have a school of four that love each others company, but sometimes they go at it LOL
