Do you have a tank inhabitant that is always causing trouble?

[Gumbies R Us]

I know for me, I can name two off the top of my head. My urchin and my watchman goby. My urchin bulldozes everything in its path, nothing is safe from it. My watchman, just likes to sling sand on the zoas next to him. So I am wondering, do you have any tank inhabitants that cause trouble in your tank?

I had been looking for a Ruby Crab for a long time. I could only find Emerald. Then my LFS had a Ruby Crab. I got him brought him home. Within a week my porcelain crab was dead, and my Clove Polyp looked like it was cut with a lawn mower. Every time I fed him he would grab the tweezers and wouldn't let go. He had a strong grip too.

I have some large turbo snails that have pushed and knocked over frags that then died from fighting with other coral that they were not supposed to be touching but the turbo snails rearranged them for battle.

I have a Tomato clownish that has picked up frags and piled them in a corner so they would die. I removed the pair to a tank where they can’t do so much damage.

two troublemakers for me. maroon clown, 7 years old and a 2 year old dottyback that thinks he's a great white. All is fine right now with stocking but anything new added gets pummeled. I want to put in a few banggai cardinal fish but will have to contemplate trading off some tankmates before i pull the trigger. The dottyback was always a jerk but the maroon clown has only recently become agressive. Maybe like me, he's just getting old and grumpy LOL

Just put the clown in timeout, problem solved, haha.

My snowflake eel is a bit of a bull in a china shop. I have to have everything glued down, or it will knock them over as it explores the rockwork.

My supposedly “reef safe” Yellow Pyramid Butterfly. He constantly picks at an Elegance, Acans, a Trachy and a couple of Acanthos.

Trying to decide if he stays in my reef or gets moved to my FOWLR.

I have 3 frags that are piled in a corner because they were in the way of a pair of Tomato clowns. They can really be jerks to me and the rest of the tank; they stupidly bite the hand that feeds it.

I could see that being a common issue with eels, haha.

Solo clownfish that I've had for 3.5+ years.

Just recently started biting tentacles off of my duncan coral (was my favorite), after no problems together for about 1 year.
*I've harped on that elsewhere and likely will again since that's my biggest frustration right now

Clown also got aggressive towards my tailspot blenny some time back. (Same -- together for over 1 year with no issues).
I don't worry about that though 'cause the blenny holds his/her own.

My tomini is a butt to my poor starry blenny

Totally agree, mine won't let any fish rest in the tank. Always chasing!

Yeah I wont get rid of him though because he is around 7 inches now and I got him from a guy with a 150/160 gallon tank. I dont want someone to get him because he is beautiful and shove him in a small tank. Plus Im attached to him so I put up with his attitude! Lol
