Most aggresive fish u ever had

[Nemo&Friends]

Four stripe damsel (humbug dascyllus), I still have her. Must be around 12 years old. Maybe because the other fish stand on their own, she is a good citizen now, but she killed one green chromis and scared to death a coral beauty.

Although not aggressive to other fish to a degree, my big ol fat Falco Hawk ate all shrimps, Crabs, some snails ...he had to go, he also became aggressive with some Clowns.

Clowns of course, but I have nice pair now of a Frostbite and Gladiator who are mating and getting big.

Of Course, Blue Damsel was the devil! What a mean turd he was...and he was a pain in the but to remove from tank...beginners mistake on that one!!

Hippo tang. The b+++ard killed a harlequin bass, harlequin tusk, blueface angel and a queen angel before I saw him and removed him.

Very strange as I’ve always seen them as being one of the lesser aggressive tangs….

 

[Flame2hawk]

Harlequin Tusk. Harley is now in my FOWLR tank.

 

[Michael Adam]

Neon Dottyback

I’ll cast my vote on 2 fish.. Neon Dottyback and tomato clown (I’ve had for 17 years and he’s a jerk)

Just a question what is the most aggressive fish u ever had or u hv in your aquarium.

I am getting rid of my two inch purple tang because she has bullied my maroon pair twice her size aswell as all my damsels into literal permanent hiding I have never had a fish come into any of my tanks and take over the entire tank to this level before

Falco Hawkfish - he was an absolute nightmare and constantly stalked his tank-mates.

Clown fish are little devils I've had them bite me countless times and some even drew blood.

I have a Percula that has murdered 2 damselfish and I Roland's Damselfish that has murdered another damsel... I'm avoiding that entire family Pomacentridae moving forward

 

[AC indochinese]

yellow tail damsel. Beat the **** out of all my new fish

 

[Andreas' Reef]

Purple pseudochromis

Orchid or the other one

Just a question what is the most aggressive fish u ever had or u hv in your aquarium.

Many years ago I had a Humu Humu Trigger that bit a smaller Singapore Angel in half. Watched it happen in disbelief.

But my Tomato Clown literally bites my hand every time I put it in the tank. So it’s a toss up.

 

[zheka757]

powder blue! but to be fair i had him with powder brown.

 

[Andreas' Reef]

Neon dottyback or Falco hawkfish

 

[FreshSaltH2o]

I had a purple pseudo that ate the eyes out of fish he was a terrible little guy.

 

[Seansea]

LUNAR WRASSE!! I would even add this last to an aggressive fish only tank. There ability to do swim by bites on tank mates , swim speed, sand diving that even triggers, puffers and groupers are susceptiable to there maniacal behavior. And as soon as you drop them the tank there is no shyness or hiding there up to no good immediatley. Unfortunalty they also look really sweet full grown with the streamers and war paint face

 

[RJT]

Neón wrasse. Harassed everyone. Even anemones- he would pull the shrimp I fed them out just so they wouldn't eat.

 

[OSFF]

Had a psychotic Midas blenny that killed 3 fish before being evicted

 

[backdraft]

Previous tank was my Powder Blue, he chased my clown tang all day. Currently in my cube it's a Ocellaris clownfish. He bites me anytime I have to put my hands in the tank.
