Last week I ordered coral frags and decided to start my reef tank in my 29 GAL which was FOWLR before. Now I knew nothing about reefing or the chemistry but taught myself while waiting for my corals. I set my reef tank up and used Kents Nano Reef A&B to start up the tank. However After using Red...

Today I found this mushroom moved over and underneath where it used to be was this thing. It is bright orange under the light and theres about 30 legs all appearing to come from the same spot. Definitely moving and looks like the legs are stretching out and grabbing things. Should I remove it...

This is the current state of one side of my poor trachy. I got him about 2 weeks ago and on the day after successfully acclimating, inflated like a balloon, ever since though he's been pretty tight to his skeleton, and now it's gotten so bad I think I can see skeleton and I'm seeking help. I've...

I have a 140 gallon tank that has been running for about a month now(no fish or corals only 1 snail and live rock. Will be adding sand shortly) and am planning on a giant cave in the middle with live rock. I want to color coordinate the tank. I want purple-ish blue on one side and a red and blue...

Hi I have just noticed some mucus looking stuff hanging off my rocks and clinging to some things. I originally set up a 29 gallon JBJ about 11 months ago and everything was going great and then it sprung a leak. I was able to manage it long enough to get a new tank, a 60 gallon ProStar. So, the...

I have had my tank going on 4 years. I almost crashed it a couple months back but brought it back from the dead. This week I accidentally dosed too much NoPoX and yesterday discovered all except one of my clowns died. I killed my green clown goby, platinum clown, hawk fish, and six line wrasse...

Hi everyone, Without going into too much detail... myself and my siblings have been in the process of cleaning out and fixing my dad's house in order to sell it for the past year or so. We all knew there was a saltwater tank in one of the bedrooms in the basement but no one has wanted to deal...

Are these diatoms still or could they be something different, or are diatoms dying and reforming? I'm confused. I'm at about.the 1 month, 1 week mark since putting biospira and first fish in. Some of this algae is Dark brown, some very light brown. Some rust colored (a yellowish rust) like...

I have no idea what this is but it looks scary af! It wasn’t in my actual tank, it was with some chaeto in another tank. the picture doesn’t do it any justice- this is when I pulled it out dead. It looks furry on its sides. Also when it was alive, it extended its body to look longer.

Hey everyone! I need a new fish for my 60 gallon for biological purposes. That being said, I would like this fish to be a utilitarian fish to keep alongside my 6 line wrasse. It is likely that this fish will be moved to a 135 gallon in a few months. The tank is bare bottom and has little live...

Hello I am very new and need your help with my Red Sea 750xxl tank. I just finally filled it and figured out kinda how to fill my sump enough so the water is running to and from tank normally. However now that the tank is on, the return pump flow into the tank itself pushes aside all my sand...

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!

Hi- I am a new hobbyist and am just cycling my first reef tank! I went to my LFS to purchase my live rock, and noticed some interesting hitchhikers. I have done some research and believe one is an Aiptasia anemone- and have read it is recommended to nip those in the bud. But don’t know what the...

i’m getting a 75 gallon custom made. i really like sps tanks but everyone says less sand or no sand because it’s easier to clean. but at the same time i’m considering jawfish which need sand and i really like more "biology" in the tank. the scape will also be quite minimalist. how can i...
