strange

Hello, ive had a pair of clownfish for about two months. Since day 1 they have been eating and acting totally normal. But today i noticed a small white spot/patch on its side. They are both still acting normal, no labored breathing or other weird behaviors. Is this something I should be worried...

Hello all! I was cleaning and moving some corals around in my tank and found that near a colony of some zoas there appears to be some kind of brown clove polyp growing around them… which is weird because I’ve only ever had firework cloves in my tank which are never brown, even when young...

I’ve had him for close to a year. When I first got him he was a normal blue face koi tang. He was sold as a tri color. After being in the new system for a couple of weeks he’s turning into this……..he’s gotten so much yellow in him and gets more and more everyday! I’m excited to see where he...

They have no holes, feel quite tough, do not bend, and have small “tufts” on their spikes. They also do not appear to have grown since I introduced them a few weeks...

I bought my first ever coral about 4 months ago, a small 2 head Torch and a fungia plate coral, I dipped them both and got a small flatworm off the torch luckily. A few days into owning the torch and watching it get used to the water and extend, I noticed a little section of bristly exoskeleton...

So I'm sitting here in my office no lights and I glance at my nano tank and I see what looks like a big white spot.... I thought it was some kind of sponge. I put the iPhone light on it and it looks like some kind of shell-less snail but pretty big... I would say 2 inches long and a solid inch...

so iv had my ricordia for awhile now and it has grown a ton sense I got it, it's probably one of the most thriving corals I have right now. The one on the left is way more blue than the photo does it justice and some of its bubbles seem to be growing much larger than most of the others. But...
