pest

Hey guys so I was just going around and cleaning algae off my frags in my frag tank when I noticed a few of these guys crawling around and was wondering if anyone knows what they are.

Hi there, I have been away for the last week and have come home to these white critters on the wall, it seems to be a shell of sorts with something inside it. I don’t think it’s a Virminted. Would like to know what they are and how to get rid of them please

Hi everyone! Greetings from Indonesia! It's my very first post here.. I need a help on identifying these annoying creatures: They kinda look like a tiny shelled snail.. Around 2 weeks ago I noticed my zoas and palys aren't opening up and also some went missing. Few days ago I randomly...

I got 20 pounds of live rock that came with a ton of cool mushrooms and I put it in my qt this morning when it was still dark I saw this caterpillar looking creature that is red with white spots and horns I've looked for hours what it could be but I haven't matched a picture yet can you help...

HELP! I bought a 20 lb live rock that came with a bunch of mushrooms and than this morning at around 5:00 am so the lights were still off I saw this red and white creature come out looks almost like a caterpillar and has spikes....I tried to identify it but I can't seem to match the picture with...

What is this? I saw this on my rock. Is this a bad thing or a good thing? If bad, how do I remove it?

Hi, Hi, i’m currently batteling dinos and I was wondering if you could help me id these. Zoom is 250x. My guess is amphidinium small cell.

Found the clearest jar I could. Placed in a piece of loose rock. Disassembled a USB LED. Soldered some spare wiring to the LED board while it is fixed in position to the lid ~ This step was quite intricate and the new circuit should be wrapped in thread tape/electrical tape and protected from...

I’ve got this pest in my tank, at first I thought it was aptasia but now I’m thinking it’s something else. I manage to get it out and and it was moving around. Not sure if this is some type of star fish iv attached a vid

Hey everyone! Had this tank running since January, and have only just noticed how large these brown algae spots have gotten. They were originally quite small, thought it may be diatoms, but I’ve attempted to take the rock out and scrub them off, as well as peroxide them, but they stay...

Hey everyone! I started a pico tank that's going to be primarily zoas, photosynthetic sponges, and Majano anemones. The kind I'm looking for are bright green with pink tips. I've seen them called graceful or tulip anemones as well. I was able to get my hands on a cool green(included a picture)...

Hey guys so I just got some new coral and these arms started poking out.. they aren’t feeding tentacles they almost look like starfish legs?

I bought this Acan about 2 weeks ago. It doesn’t look so great and it hasn’t been improving. It appears to be receding and just seems generally unhappy. Last night, before lights out, I noticed this weird thing on the edge of it and I watched it for a few minutes. I didn’t see it move at all...

Bought Marco rock right away I put it in the tank, got 2 coral from Petco: mushroom and Kenya tree after a month in the tank with 3 fishes I ordered more Marco rock to start aquascaping I think is called, break the rock and redesign it, so the new rock came I broke it and since it wasn’t enough...

i have an 80 gallon (90cm x 60cm x 60cm) with a flasher wrasse, royal gramma, algae blenny and kliens butterfly. i will be returning the butterfly as it has been nipping at my sps. is there a magical fish that will eat aptasia, flatworms and nudibrachs? i don’t really want a halichoeres (sp?)...

I noticed this on the rear of my tank last week while doing a water change. At first I thought it was a snail. This week, still there and no movement. Is this just something stuck my tank or something growing?

What is this on my frog spawn ? Should I remove it? Or dip it?

Hi Guys, I've had this "Mini SPS Colony" in my tank for about 3 months, it was growing quiet well to start with but for the last two months its been slowly losing flesh, I originally thought it was just down to shading so i moved it to pretty much directly under one of my lights to try and...

I’m servicing a clients tank and they have these small aphasia looking things everywhere with an unusual (pretty?) coloration. They seem resistant to aptasia x. Historical pearlscale butterflies will eat them I’m told. Anyone know what these are?

Just noticed these hanging off my Zoas today. Tank has been fine, I’ve got 10 trochus snails and 2 clowns, zoas, and an elegance. Found 1 aptasia and a majano which I’m dealing with, just in case that could be the cause. If you need parameters, let me know!

So I noticed some closed up polyps over the last few nights and I saw these little spots that thought could be sand from me stirring to clean the glass but upon inspection we’re moving. Not sure what they are if they’re bad or how to remove them any help is much appreciated

A couple days ago I didn’t see any of these. Now, they are everywhere. What are they? Thanks for the help! Picture attached.

Hey all I think I just found a tiny aipstasia on a new frag, and I’m not sure what to do. I’ve only just cycled my tank and have my first clowns and corals added, but I saw this and now I’m worried. If it is aipstasia, what should I do?? I don’t want it to spread, but would feel horrible...
