Is this zoa being eaten by something? All the other zoas are doing well, both on the frag and in the tank. Its just this one polyp. Its been in the tank for around 2-3 months. they are loosing colour in the side where the "lashes" are retracted/gone. its been like this for 3/4 days and i think...

Here is A Very Inefficient Method of Treating Aiptaisa I discovered a few weeks ago on accident… for anyone who is curious: 1. Submerge infested rock within sand 2. Wait for Aiptasia to detach from submerged rock and crawl towards the surface of the sandbed 3. Scoop up the Aiptasia As this...

I have noticed this snail pop up in my tank about a week ago, It looks quite pretty but I don’t know what it is, could someone ID it? The inverts I currently have in the tank are: Randall’s pistol shrimp, cleaner shrimp, 1 trochus snail, 1 nassarius snail, 1 strawberry conch -it’s grown quite fast

I woke up this morning and found 14 of these strange little guys creeping up my glass in my saltwater tank. Can anyone help ID these? I have searched high and low and can not find anything similar. https://studio.youtube.com/video/5a9Hveudz3s/edit

I spotted these strange tentacle looking things on my zoa rock. Is this aiptasia? I moved the rock to a quarantine tank for the time-being. There were a few other rocks very close to this one. Should I take them out as well and try to salvage any Zoas I can?

Can anyone ID this?

So I’m new at this salt water thing and this is my first hammer. I noticed this “pineapple” shaped growth forming on the skeleton of my gold hammer. Anyone have any idea what this is or what it could be? Any input welcome. Thanks for helping a novice out (in advance)!

Started noticing these little hair lookin guys in spots on my rock, wondering what they could be? Hydroids maybe?

I was wondering if there is any nano fish that can live with clownfish and will eat both of these pests? Thanks for any help in advance!

What are your thoughts on purging mobile pests from live rock with hypersaline water? Explanation from KP Aquatics: "(Optional Step) Undesired critters (we really don’t like the word unwanted pests as every creature has a purpose in life) can be removed by submerging the live rock into a...

hi again yall! weird mucusy, matted web looking stuff in a low flow low light area in our tank.. been around for a little while, doesn’t seem to be bothering anything but it’s ugly & we are curious if we should remove this or leave it alone.. it’s somewhat like an algae growing.. fish, cuc, etc...

Hello! I’m pretty new in the hobby! Today I just noticed this kind of red worm on my euphyllia glabrescens… Is it vermetid snail? If not what could it be, the bottom seems attached to the body of the coral. Thanks for your time!

There is no triangle head...

These are very small. Can barely see them with my eye but I used a high power magnifying glass over the camera lens to capture an image an video. Please tell me these aren't bad. But if they are how do I remove them!?

hi y’all! bought a frag from our LFS and this was at the bottom of the post.. looks like some sort of snail, any ideas?

Yeah, I got no words here, it seems to have sprung up randomly (like all the worst algaes do) and didn’t appear near a frag or anything, what is this? Is it some sort of super-cyanobacteria? Will it harm my corals or snails? (I’m afraid the latter would probably eat it regardless) And most...

I just purchased a zoa frag and during the acclimation I noticed that the plug has this red hard almost mushroomy looking thing what could this be?

I’ve had my tank set up for over a year, and never had added any crabs. My tank is a mostly fish only tank, with 2 anemones and some GSP. So I was caught by surprise one night when I spotted a mysterious crab on the rocks. My theory is that maybe when I was adding pods to the tank, there might...

Hello all, I'm fairly new to reef keeping, and my tank has been established for about 5 months. Stable parameters all in range, alk around 9.3, nitrates 5 ppm or lower, and phosphates sometimes on the high side of .5 (I use a reactor to bring it down below that). Salinity is 1.026, calcium...

I know they aren't too harmful to things but I just don't want to have worms burrowing into any of my corals. And Im worried about the future of my tank. I have some spionid worms in my sand bed. Anyone have any luck with creatures / fish that eat these worms, Ways to control the population, or...

Good evening just wondering if anyone can tell me what’s this growing in my tank

I’m new to the hobby. Please disregard all the algae, I’m still in an ugly phase. There’s something red growing on my toadstool (shown in the middle of the bottom picture) and there’s something else attached to my favia (shown in the middle of the top picture). I’m wondering if either of these...

Hey Reefers, So I went to my tank to do a bit of maintenance this evening. So I put my tank in feed mode to stop the gyres and turn the return pump down to 1%......and when I turned on the tank lights, to my surprise, I see thousands of very tiny worm-like creates swimming around. I am...

I bought a mushroom frag today which actually grew on a snail shell. I was debating on dipping it when I big Orange work came slithering out for the shell! Is this something I should try to get rid of with the dip or introduce to my tank? I currently don’t have any in my tank It actually looks...

I just noticed a gray hole on my cyphaestrea? Params: Nitrates: 7 pH: 7.8-8 Alk: 8.4 Mag: 1440 Calc: 500 Temp: 80-81 all my other corals are doing well and growing, granted they are easy soft corals. The cyphaestrea looks like it has a gray spot on the right which doesn’t look like bleaching...
