sand

Hey all, My coraline algae that was once purpleish, is now bleaching white or a faded grey. I'm assuming it's my lighting because parts that have less light are still purple. Behind my anemone when it shrinks up, the coraline is still purple behind it. It started with white spots taking...

At school in Aquatic Science we are setting up 12 tanks for different projects. One of them is to study a cat shark egg from hatching in a 55 gallon........ I know, I know. My question is should we consider sand and rocks in there or just leave it bare bottom? When the study is over in a few...

Do you have to use live sand? or can it be just a regular substrate? Thanks in advance

I just lost my Mandarin Dragonet and am looking for another sand-dweller with some cool mannerisms. I used to have a diamond watchman goby, but it jumped out of the temp tank when I was moving houses. I've tried other diamond watchman's in my old 120g, but they would always disappear and then...

Greetings! So I am fairly new to salt water aquaria -- I kept a planted freshwater for a few years -- and things are going pretty well so far. A short time ago though I discovered a few new "guests" in my tank. They look to be small tendrils/worms encased in sand tubes, which based on a bit...
