Yes. The web can irritate a coral and prevent PE. If there is no PE, the coral can die and be overgrown. That photo is from another reefer on RC,...
I'm not sure what the best source of berghia nudibranch are. Peppermint shrimp work wonders though. They will try to steal food from corals, if it...
In large numbers they can irritate corals, they don't "sting" per say. That is very unusual though. If it gets to that level, usually there is...
common vermatid snail. They shoot out a web to catch food. Annoying, but harmless.
65% Well, idk, I can't give you a real number, but probably over 50% are fine. The key is to feed them a lot. This can be a problem though, as...
What kind of clownfish and how big is the frogspawn? I've had OCs in my frogspawn for many years without issue, but it is a fairly large frogspawn....
Corailline, Dingo and MSA Corals have given good advice. You also may need to use a toothbrush to get some off the rocks. There is some conflicting...
Sounds like a bacterial infection or a predator. Sounds like you just got him, is he in QT? If not it's probably safest to remove him and put him...
Sure, no problem. Most of my info comes from Scientific Journals, hobby magazines such as Advanced Aquarist, Reefkeeping and Coral Magazine. As...
Yeah, need to know what corals you plan to keep.
Right, great points :) Also, here is some extra info, for anyone not suffering information overload: Although the exact mechanisms are largely...
um, maybe. Not always however. A pair of polarized sunglasses is probably cheaper than a new sheet of glass and free if you can find someone to...
The ocean has a lot of particulate material floating around. It's more natural that way :) Also, as others have said, changing out the filter more...
I'm not familiar with the cone style, but should be the same principles though. I have the one in the video and have it set up similarly.
That said, the crab seems to have some pretty big claws. I wouldn't trust it ;) Crabs are opportunists a little hermit can't doo much damage, but...
Some background info (or just see conclusion if preferred): So the algae is found in vacuoles (called symbiosomes) within the corals endodermal...
Well, no one else followed up on the question and I have to leave for the afternoon, so I'll start LOL. Some of the more important conditions...
Right, so zooxanthellae being an algae(actually, more specifically a dinoflagellate), will grow under any conditions that would promote algae growth....
Well, think of it this way: Corals have their own pigmentation, and they also host zooxanthellae, a golden brown symbiotic algae. The zooxanthellae...
Light and inorganic nitrogen. Anything that can increase zooxanthellae population density within the coral. However, as far as I'm aware...
