Bully Blenny - what to do...

[Wonf]

Hi all,

Would like some advice/opinions on what to do...

Here's where I'm at:
- Just added 2 Diamond Gobies to DT. They spent 3 days in a Social Acclimation Box. First 2 days, my established Lawnmower Blenny would charge the gobies when they left the PVC shelter if they were in sight. On day 3, he stopped charging and only flashed by the box. This morning, after watching on/off for a couple hours, saw the Blenny would swim by the box but ignore the Gobies even when they were in plain sight. Let the Gobies out.
- The Blenny starting charging at the Gobies, and after hours of harassment (not getting any better), I decided this wasn't going to work and FINALLY caught the Blenny. (more on this if someone wants, it wasn't easy catching the guy with minimal tank manipulation).
- Currently have the Blenny in the Acclimation Box in the Sump.

Options:
1. Put the Blenny back in the DT in the Social Acclimation Box for x amount of time. (if so, how long or what do I watch for before I let him out?)
2. Leave Blenny in Sump for x amount time. Then let him back in the DT. (what's a typical time before the Gobies get established and/or the Blenny forgets he was established?)
3. Blenny will never get along with Gobies and he's gotta find a new home...

Thanks in advance...

Blennies can be very territorial some bullies some not. They are wild animals so personality from fish to fish varies. I had a purple tang kill all my fish over night after being in the tank for months with them added a Fox face and it triggered him to kill 4 fish total over night.

The Blennies aggressiveness definitely started rubbing off on my other fish... All acting differently than before. I'm in Valencia, will keep you in mind if I end up giving up the Blenny.

Try keeping him in the box for a few days to let the gobys get settled in and try rereleasing the blenny. Or put the blenny in the sump for a week or so the put him back in the tank. If you can move some rock around that might help disrupt the territory.

When I added my blue tang, my Blenny relentlessly attacked her at first. It was so bad she had visible purple marks on her body. I noticed the behavior within the first few hours so I left the light off and covered the tank for 2 days, when light came back on he attacked the tang much less, and now they get along well and are always together. I hope it goes the same way for you!

Thanks... sounds like maybe his "timeout" in the sump may work... Still probably going to keep the Blenny in the Social Acclimation Box when he re-enters the DT... Any way of knowing whether or not he'll still be a bully when released while he's in the box???
