Whats the biggest pest and/or hitchhiker you've seen in your tank?

I found a big ol' asterina on my glass today and wanted to see what others have discovered. U.S. quarter for scale!

That's impressive... ive somehow, knock on wood, managed to avoid getting bristworms into my tanks thus far.

I have a bunch of smaller ones, but that was a big boy. Not sure how I felt about it lol

Biggest pest: Momma Fireworm

I think I finally caught momma (fireworm)

Not really an ID thread as I know what it is but it’s a hitchhiker lol. So some of you may be aware that I’ve caught the occasional fireworm. Well most have been 2”-3” or so. Well I think I finally caught momma. This one is about 1/2” wide and about 7- 8” long. I literally just grabbed her...

Biggest Hitchhiker - Ol’ Curley Que (had to use the flashlight as my halides haven’t kicked on yet and excuse the hair algae and Cyano. No CUC will go near the anemone so I’m guessing it’s got a potent sting)

Chiton. Unknown species.

There's probably some in there you just haven't seen yet.

I've got a breeding population of chitons and it takes them a couple years but they eventually get to that half-inch size.

I'm sure theyre in there somewhere, but i choose to live in blissful ignorance for the time being lol

These guys! I believe they’re mushrooms with deformed nasty looking, bubble-like structures? They grow like weeds and overtaking my tank. I’ve been trying to kill them with kalkwasser paste but no luck! They kept coming back with a vengeance! What should I do?

Ciągle wracali z zemstą! Co powinienem zrobić?

I've got about a 4" Bristleworm that lives inside of a dead urchin shell.

Recently found this elephant slug, it’s about 4 inches long. Lol

This pair of red mithrax crabs hitchhiked in on some KP Aquatics liverock. I kept them for about a year then rehomed them because I converted the tank for pipefish, but they were pretty neat. The female laid eggs in the jar lol
