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

[Righteous]

I highly advise against it.

Count me among those who don’t know why. I’ve got 5 blue/green chromis, all the most peaceful and keep to themselves. Maybe differences among species?

My blue/green one is really peaceful too

I had blue chromis three were in a school and they were great together.

mccoskers flasher wrasse, candy hogfish, melanarus wrasse, talbot damsel, most zebrasoma tangs i’ve had.

McCoskers? Really??

 

[carbasaurus]

Black bar chromis. Guidebook stated it was peaceful. In my nanotank, once he was in, no more new comers allowed as he would pound them relentlessly

Even worse was a square tail bristletooth tang (similar to Kole Tangs but much more aggressive in my limited experience). This was in a 200 gallon tank so aggression not due to overcrowding or cramped space. Mine decided he hated gobies and would hover by their burrows. If the goby ventured out he would shiv it with his tail “knife”. He killed one outright and wounded another. Really quite psychotic.

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

Ive got 6 tangs in the tank with some wrasses and the worst one is the Two Spot african wrasse. beatiful wrasse but it eats the small cardinals and eats the snails and hermits.

Before Hunter's famous wrasse compatibility chart existed, I bought a beautiful Sunset Fairy wrasse that turned into a nightmare. He bullied every fish in the tank even tangs and damsels LOL

I had two and then one. The last one went nuts and tried killing my other fish. I think it went crazy from being alone.

Yep. Was fine at first then turned into a beast towards any other small fish. It was weird.

In a tank with the following:

Sailfin Tang - Dominant but not agressive
Blue Hippo Tang - timid
2 Ocellaris Clowns - model citizens
Six line - main jerk (killed a royal gramma)
Blue Damsel (yellowtail) - jerk 2
Lawnmower Blenny - # 3, but not so much
2 Bangaii Cardinals - model citizens

Gotta love the cardinals, floating around without a thought or worry in their minds.

Powder brown tang used to go crazy with new additions but he's calmed down for some reason

Never heard of a two spot wrasse before but after looking it up, no doubt it's a beautiful fish but I don't think any fish is worth that sort of destruction

My flasher would always sneak attack anything his size or smaller, harmless but relentless

Beautiful fish I can see why you got it, I had a katherines wrasse that had the same demeanor. Bullied the hell out of my flame at the time and had it out for my gobies.

That really does sound psychotic! Had a similar experience with a yellow eye kole tang, everything was great the first day, second day my blue star leopard came out of the sand and my kole tang was acting like my blue star was a new arrival, absolutely pounded my wrasse. Took the kole tang out and reintroduced it several times, same thing would happen every time, but the kole tang eventually died to ich so karma got him hahah

 

[Hermie]

Peppermint shrimp lol but it was only the females that were berried, they would be tearing apart anything and everything (including my snails).

I looked it up too and most of the ones shown are wrong, his is the African one which looks a little scary haha.

 

[ckozma]

My menace is a plain ol female clownfish. She will not let me into the tank to do anything without being bit and chasing her with a net with the other hand is really difficult. She is not very scared of that net either anymore haha.

 

[bnord]

Have a splendid dotty in a 180 balanced size and species tank. It never chases anyone and a delight to watch as he shows curiosity and travels the whole tank looking for snacks
I know it’s lucky but i a right sized tank they can be a delight

Seconded.

No dottyback can be called peaceful.
