Oh COOL.....or Oh CRAP!?

[revhtree]

For me it's mostly been a positive thing.

What's your response when you see a new unknown critter in your tank?

crap, definitely crap

 

[Gumbies R Us]

Depends on what I see in the tank! Could go either way, haha

OH CRAP!!!

 

[rayadog]

I caught a glimpse of something last night and literally said oh crap. Thought I caught all my crabs… unconfirmed but it’s likely a crab.

Mmmmmm...Looks like I'm on the unpopular side of this...But I tend to say:

I'm with you. Everything is cool until it isn't. Crap comes later.

It can be cool, but at the same time, a new critter appearing in the tank can also mean it came in on a coral that it was feasting on. Oh Crap!.

Like this little guy I caught in a new millie a week or so ago:

Cymo melanodactylus

I say cool until I either ask here and someone says it's bad or I'm able to figure it out via Google.

As mentioned, it really depends on what it is. I mean, some hitchhikers I have include... limpets, two small random bivalves, numerous feather dusters, sponges. I've been lucky with my TBS liverock purchases. I haven't had any unwanted crabs! Everything else can stay, just not certain crabs.

He's definitely cute and fuzzy... but those pinchers say it's a no-go!

Look at those blue eyes, though?!?!?

I named him Frank Sinatra before his burial at sea.

Love the surprise gifts in live rock. I set up tanks just for them if necessary, yes even mantis shrimp and . What is a few critters that are amazing.

 

[mfinn]

I got in a few saltwater mussels that have grown to a few dozen in one tank. They have lasted more than a year.

 

[Matt L]

It depends on how much damage they can do.

 

[Randy Holmes-Farley]

I think of my tank as an ecosystem, and am generally happy to see new things. Sure, some things have drawbacks, but few are so bad that they merit a lack of respect. lol

Really depends I’ve seen things by accident under a microscope walk across my slide. Like the time I found a black bug. Literally looked like a spider. Found out they are just scavengers and eat Algea and never had any problems with them and coral. Although some might disagree if they are bad or not. The more diversity the better

 

[steveschuerger]

I generally have no problem with things that come in on rocks. Right now I have a small wennerae mantis that came in with the live rock. Sure it’s been eating snails, but if I had hermits the same would happen.

Even when you find a Eunice worm???
