So what's been your coolest hitchiker or worst you have found

[jayala12]

. Neon green toadstool I got on some live rock I bought off craigslist

here it is today doing great ... survived my tank cycle and hurricane Harvey (no power for 8 days )

Coolest hitchhiker I have gotten in my short time reefing was a small emerald crab. Worst (so far) was an aptasia anemone that was gotten rid of before it spread.

Some type of blasto it seems

+1 on TBS rock. I've gotten a TON of cool hitchhikers on the rock I got, and I only bought the 10 gallon "package." It was well worth it. Urchins (lots of urchins), crabs (not just baddies but also some smaller varieties including an acropia crab and a decorator crab), corals, limpets, and I did get not one but TWO mantis shrimp!

I like their sand, too. It looks more like the sand I would find on the beach when I was a kid.

I have tons of Stomatella Snails in my tank last night I counted 9 on just a single rock

I only have one that came in on a small piece of live rock that went into my Frag tank... that thing is a workaholic. I need to find more.

 

[Cnidoblast]

Best: Stomatella and cool looking zoa
Worst: Green Bubble algae

 

[radiata]

Neatest thing I ever found was a pair of dime-sized urchins that came buried in 5 lbs of live Florida sand.

Coolest was mushroom coral. Just got a new light for my tank so I hope they grow and spread.
Worst was Aiptasia which I keep under control with two peppermint shrimp.

This has to be coolest for me so far.

I have seen this guy once. Saw him on my turbo snail and then he “stood” up for a minute like he was saying hi. Then he crawled down the backside of the rock and I haven’t seen him again. Lol

I dont have any pictures but once i went to the LFS and purchased a few extra rocks for my xtra small pico tank. I looked in there the next morning to check on my clowns and they both were dead as were all the cuc. I re purchased and chocked it up to my error that they all died even though i didnt see a reason after testing all the known parameters. Everything tested in range and thus i started to scratch my head as to why. Then the next morning i got up to find everything dead again. I tested and everything was still in range.

I decided to try once more. Then in the middle of the night i had an urge to get up and go check the fish to see if they had died like the others. I walked up to the tank and to my surprise i seen what appeared to be a very small snake like creature almost resembling a sea crate. I knew this wasnt possible since the crates are much bigger of course and tried to grab it with a set of hemostats. The creature shot back into the rock work and disappeared. He was making an attempt at one of the fish and the other was already dead.

I did some research and found out what i had what was called a proboscis worm or nemertean worm. They are really nasty little creatures to come across as they have a poisonous tip on the end of their nose that they use to incapacitate their prey.

Ended up giving the rock back to the LFS and they got tired of trying to catch him so they dropped the rock in a bucket of bleach.

good riddance.....

My best hitchhiker: I bought a carpet anemometer. W hen I got it in my tank I found six baby Percula clowns hiding in it.
My worst: Red flatworms

 

[mstockmaster]

I've had a few hitchhikers including the common stomatellas, sponges, etc.

I have a large population of isopods in my tank. They all seem to be the same species and are all peaceful detrivores, very active at night and fun to watch scurry about.



But the coolest, weirdest, thing I've seen in my tank was a number of polychaete worm epitokes. I'd you're not familiar with these then look them up, very interesting.

 

[XNavyDiver]

Adding to the list: I just found a tiny commensal acropora crab in my garf bonsai colony. It's going to be tough to get a pic, but this is exactly what it looks like.

 

[JoeIII]

I got a 3" red mithrax crab as a hitchhiker once, it was so cool. Wife named it "pinchy"

 

[Wiser]

I have tons of awesome hitchhikers from TBS. The best are porcelain carbs, serpent stars, Mithras crabs etc.

Worst Gorilla crabs and 2 mantis shrimp left (although I might let them stay)

but this guy is the most interesting........

How's this fireworm rate?

Gosh is that a fire worm. I thought they were bristle worms, are they bad cause I have lots. I thought they cleaned up.

Worst thing I eva got was these teeny tiny jellyfish that wiped out my copepod population that I had built up over 12mths. It only took them about a week to destroy everything. Too small to catch and I couldn't find any information about how to kill them other than "they will die out from lack of food"

 

[NowGlazeIT]

Red planaria flatworms. Boy they are annoying. Dip your stuff folks !

Same here
