Which fish turned out to be a menace in your tank?

[QuarantinedCorals]

Hey guys, I'm curious to see if you've ever had a fish that was said to be peaceful but turned out to be a menace? For me it was my male pintail fairy wrasse, he would bully everything that would come into the tank, especially other wrasses. Share your experiences

1. Roland's Damsel that I read over and over is peaceful. It currently has a gramma trapped in a hole. Fishing hook is on the way for him.

2. Longnose Hawk that became aggressive with others. Back to the store with him.

3. Male clown that was obsessed with trying to kill Firefish and Chromis. I'll just say he's no longer terrorizing anything.

Yellow tail damsel for sure! Only paid $5 for it and soon learned why it was so cheap!

neon dottyback. I cannot add shrimp in the tank after adding the neon.

It depends Had a Passers Angel that was bad, had a Bicolor Angel that was bad. Had one powder blue tang that was bad 2 that were great.

Kole tang. Surprisingly. I have 4 fish now. 2 clowns. A fire hawk and a long nose hawk. No nipping or anything but the flame hawk is sooo territorial. I’m looking for one more fish to add that will subdue him a bit and just be a mother tank mate. Any suggestions?

I have damsels, 2 orchid dottybacks, clowns, 13 tangs, 5 royal grammas, assortment of wrasses inc six line (all this in 750 gallon system) but the ones that have given most trouble/killed most fish were:
- redfin wrasse. Has chased and killed about 5 different wrasses
- bullet/brown barred goby. Has chased 3 different sand sifter gobies and an algae blenny. Refused to let them out to eat etc.

Darwin clowns. Mean and nasty to my helping hands

Orchid dottybacks can be nasty little fish

Seconded.

No dottyback can be called peaceful.

My yellow tail headbutts my hand when it’s in the tank

Seconded.

I just got a dottyback. Hangs out in a hole in a rock. Seems mellow. Eats like a pig though
