pest

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...

I’ve reviewed and searched for an answer but haven’t successfully located what I’m looking for. I purchased a number of frags and a cabbage rock from my local shop. I noticed, what I thought, was bubble algae on a frag, but when I went to manually remove it, I found the spheres to be very firm...

Looking for an ID on these, I’m pretty sure they are vermatid snails. New tank, 16 days in with mostly dry rock but I got a whole bunch of rock from a a tank shutdown which had been out of the tank for a week. It’s that rock which is infested. I have three seperate rock towers and I’m thinking...

Hey All!!! I have what I think is a sponge growing in the tank. Most in shaded areas but I did have a lot growing on, under, and around one of my big leather flower corals. Unfortunately I didn’t get a pic of the thing on the coral but did take a few pics of the stuff on rocks. Help identifying...

Hi guys, Relatively new to reef keeping but I have came back from Christmas break to find a couple of snails in the tank that either weren’t there before Christmas or were too small for me to notice. They appear to be white shelled with tiny red stripes, and not more than a few millimetres...

Hey everyone, I found this guy in my aquarium, I took it out just in case it’s bad. Would anyone happen to know if this is a good guy or bad guy for future reference incase I see more.

Any idea what I’m working with here? It’s on the glass and there’s nothing similar on/near my montis. Looks almost like a berghia to me, but I’ve never had them. I’ll try and get a better photo of the top.

Can anyone ID this crab for me? I found it in my tank this morning. It’s about an inch long. I’m not sure if it’s just the shell, as it’s quite soft and not moving. Thanks

I noticed these small snails all over my sump, filter socks, etc. I haven’t seen any in the display as of yet. I do have 2 turbo snails in my sump so I’m not sure if it’s possible they laid some eggs that hatched ? I doubt it as they seem to be really flat. I attached some pictures of one of the...

Hi. I've noticed a few of these pests (I assume) on my live rock. Does anybody know what they are and if I should remove them? Thank you!

I'm having an issue with my colony of Zoanthids they start to demise :( I had no idea what could possibly cause that some of the polyps won't open. Suddenly I've found tiny slug-like creatures pinkish in blue light. Does anyone have an idea what it can be? And how to fight it???

Can someone help me ID this? Little orange looking thing poking out the bottom Was using my flash light looking at the tank and seen this thing sticking out the side? I stuck my hand in there and it like retracted, Ended up pulling the coral out, took a knife and like scraped the bottom to...

I left my house for 2 days and came back to my tank with these guys in here. Anyone know what these are? The video isn’t very clear but they look like baby shrimps. If this helps, I turned off the lights during those two days to try and get rid of some of my algae and see how they would respond...

I've got an asterina problem that are munching on my zoas. If you are in Palm Beach county and you have a single Harlequin shrimp I can "rent" out for a few months, that'd be great. I'd buy it upfront and return it back to you in a few months for a small refund, or find a new buyer if you do...
