hi -
i'm a newb and wanted to know what these things were in my tank.
is this what they call "red slime"? is it harmful? it hasn't grown or spread in over a month and is easily removable - is that best?
what is this? it closes most of the days and as soon as i feed, it sprouts and opens attempting to catch whatever teeny particles it can. it's really cool to watch and i have no idea how it got there. does it grow on it's own or just came with some of my live rock?
why is some of my substrate or rubble turning a copper color? this is a first. all my levels are in check but i think in order to have the red slime i probably have high nitrates and lighting which i supposedly don't have.
lastly why do most on this forum only have a tiny bit of sand in their aquariums? i got a bag of crushed coral and rock from the LFS to add a bit of texture and a warmer feel to the tank, is this bad? i have all kinds of 1cm to 3cm creatures under the rocks in the sand creeping and crawling all over. normal?
thank you for all your guidance and help!
