I picked up a Black Cap Basslet to replace a bullied Yellow Tail Damsel. The bully is a Fiji Devil Damsel. The Basslet has found a safe spot in the rocks for now. I need to get the Fiji out of the tank for peace. I don’t want to pull all the rock work out,but that maybe the only choice. Looking for suggestions to catch the bully.

I recently acquired a baby yellow tang for my tank, but my purple tang has been exhibiting aggressive behavior towards it. It chases and bites the baby tang, prompting me to create a DIY acclimation tank. Additionally, I purchased a mirror to attach to the tank’s glass. Considering these factors, how long should I keep the baby tang separated from the purple tang?

My damselfish started to defend its territory under the rock and I saw people say it could harm others fish, but mine seems to be just nibbing the female clownfish. Was it safe?

Copperband update… 👀

Making progress.

He’s officially off brine and now eating live oysters way more aggressive feeding than I expected.

But… the tangs are on him.

• Purple Tang leading the charge

• Bristletooth backing him up

Tried the mirror trick helps while it’s there… then they remember him again 😅

And yeah… I went for it.

He’s now in the general population 😂

So far he’s holding his own, staying active, and still eating, but definitely getting tested.

Not calling it a win yet… this fish has humbled me before.

For those who’ve kept one long term—

when did you release yours?

Did aggression ever fully stop?

Copperband attempt… again.

A few days ago I bought a Copperband Butterflyfish, a fish I’ve always loved but never had long-term success with. Either they stop eating or slowly fade away.

At the store he was already eating brine shrimp, which gave me some confidence.

Right now he’s in an acclimation box inside my display so he can observe the tank before release.

My biggest concern besides feeding is aggression from my tangs:

• Purple Tang

• Blue Eye Bristletooth Tang

I’ve been researching the clam on the half shell method for feeding and also the mirror trick to distract the tangs when I release him.

Let’s see how this one goes. I’ll document the journey.

Anyone here successfully kept a Copperband long term?

Farewell destructo, job well done... traded him in today for a few nassarius snails and an electric blue hermit. Such a pretty urchin but he's dragged too many corals into unwanted battle. He won the old war on the red turf algae now he can cause havoc in the shops 500g display for the rest of his days.
