Is this coraline on the rock? If so it is normal for there to be some die off as it adjusts to your new tank. It will come back it takes time. Don't go and add anything other than doing water changes as you shouldn't be using much calcium in your tank right now. Just be patient
I think it is only a couple of months old. Though coraline should start pretty quickly. Sometimes changing lights etc will shock it a bit, but it should come back. People always rush and add stuff like purple up etc which is just glorified calcium and not necessary.
i bought some of that stuff a while back im talkin like before corals*crazysmil now i actualy use it though to keep my calcium up around 400 *SUPERSMIL
The green stuff should turn purple over time. At least that is what I noticed with my tank. You should be worried with alk and CA. Those are two very important elements in your tank. Brown coraline?????
well my crabs arent really eating anything...probably cleaned everything...
so they decided to eat a snail.......wat disturbed me the most was that my nass. snail was in on it too...so i added some flakes so they wont eat the other snails...
i had only like 2 nassarius...then one was missing, then i saw a blue leg hermit with a new home : a nassarius shell.
I've seen blue leg hermits munching nerite snails...they can eat 'em. No i have 0 algae in my new tank so they need to feed...it's possible
