Loaches Online Forum

What size are your angels & what kind of rainbows? I can't imagine mine ever harassing even half grown angels or larger rainbows...threadfin rainbows...maybe...they're so small & such delicate, slow swimmers. Frankly, I'm shocked at your experiences!

I tried to keep juvenile skunk loaches with CA cichlids years ago & that was a major problem... but sids, never IME...

Oddly enough I've never seen them nip a threadfin, maybe because they chill near the top.

I've seen them biting my wapoga river rainbow and my medium sized Angels. My Wapoga actually got so pissed off he charged at them and scared em off.

They certainly don't do it very often though. It's just like you'll occasionally see one get a bee in its bonnet about a fish being there and then chase it about a bit.

I came to the conclusion that the nippy Sids were probably very hungry (starving).
