What is one fish you refuse to have in your tank?

[Gumbies R Us]

We all have that one fish we just aren't the biggest fans of. Maybe it is past experiences with that fish, current compatibility with other inhabitants in your tank, or just a general dislike. I am wondering, what is that one fish you don't want to have in your tank? Curious to see what everyone says!

I will always have a clownfish pair in all of my tanks, but I'll never stock a maroon.

Never have another triggerfish again~ terrorized all the other fish

 

[Amstar]

Neon dottyback - holy terror

 

[Alexraptor]

Bicolor dottyback, good god that thing is nasty, ripped apart the first shrimps i ever had, like tissue paper.

I will never add another foxface to my tank again. I tried 4, and they all went after my trachyphyllia corals.

Clownfish of any kind. Most overrated fish in the hobby

Six-line wrasse is on my banned list. Although beautiful, they don't play nicely with their tankmates.

This seems to be common with those fish haha

Tangs and six line wrasse. I don’t think people know how big and active tangs are in the wild and six lines are just too aggressive and there are better alternatives.

Team foxface!

Great white shark way to aggressive and hard to feed.

Bicolor blenny - at least not in a reef tank. I have never seen a fish mow through favites and leptoseris faster. Blennies are great fish, but imo some of the Escenius blennies are a risk, other than say a Midas blenny.

 

[flashsmith]

Any sand sifters. Not only for the mess but a double no because of their uncanny ability to carpet surf when the lid is off. I'll also add an invert. Nerite snails.

The one fish I will never have in an aquarium again is a Undulate Triggerfish. The one I had I purchased for my Predator tank. I had a Lionfish and a Spotted Grouper in a tank then I added this guy to my tank and He immediately was nothing but a Hassell. Attacking the other fish. Constantly chasing them to the point the water was coming out of the tank at times. I ended up giving him to the LFS to rehome him. So never again.

Other than clown fish, I'll never put another damsel in my tank. They, as a class, are just devil fish. When I was young and dumb, I put a blue velvet damselfish in my tank that then proceeded to kill three other fish. Never again!

Nemo. He keeps trying to escape. Keeps going on and on about finding his daddy.

I'm too new in my reefing rebirth to have had a bad fish, but I had a yellow-tailed damsel back in the day, and won't go there again.

I'm staying away from tangs. I've never had good long-term success with them and that is largely due in part to never having a tank longer than 4 feet. You have to have the room for them, or just don't. Maybe 1 out of every 4 was a "keeper" and the others were losses. I could keep bristle tooth types a lot easier for whatever reason, but even they will get big eventually.

I know I MIGHT regret it, but I have a Flame Hawkfish coming next week. I have never owned one in all my time doing this and I have always wanted one, so I guess I'll be back to complain about it in a little while. I'm happy to finally be doing it.

You practically have to tear an entire tank down to get them out once you put them in. And they'll be the last fish to die.
I've had ones that nipped at polyps seemingly just to get me mad. I think they are actually one of the most intelligent fish as well. So it may be true.
