Bicolor has to go!

[MT_is_a_Pisces]

I will say I'm a newbie. Started tank October 2015. Tank has been okay, no major issues. I wanted some color the go with my 2 clowns, 2 cardinals fire fish and 6-line wrasse; so I added a bicolor dotty-back (pretty color) about 5-6 months ago. Needless to say I recently lost 2 fish. Do I send it to timeout?

Send it, of course it could be the six line.

Could be the dottyback, could be the six-line, could be one of the clowns.

Dottybacks and six-lines will go rogue at some point - it's just a matter of when IME. Depending on the size of the tank, clowns can also be very territorial.

6 lines turn into huge a-holes as they mature. It's a shame because they're beautiful fish.

The two fish that were terrorized to death was the smaller cardinal and the six-line

We had a bi-colour DB and it terrorized everything it could. Went back to the LFS we got it from.

Last week I posted this exact story and Sk8r started a similar thread. That bicolor dotty b^&*h has offed 1 of my firefish and a blenny but for whatever reason is now leaving all of the other fish alone, including the remaining firefish that she used to chase. As soon as I get a trap set up, she's in the sump then the LFS.
I figured a 120DT was big enough. Never again with this fish.

It's likely the bicolor. I've had issues with them in the past. They get very territorial and nasty.
