Hi Myka,

I was planning on having only two or three small/medium sized rocks on one side of the tank separated by a short piece of glass running from front to back, to prevent the crabs from gaining access to the rest of the tank.

If the crabs show any signs of getting over the wall, I will remove them.

Do you think scraping off lots of the scypha sponges will result in an ammonia spike, or will they stay alive for awhile and then die off slowly?

Hmmm...well why would you want to do that to your tank? Kinda wrecks the look I would think. I don't think they'd get over a full divider.

I don't think you'll have any troubles with ammonia or nitrite by scraping the sponges. Many of them will still live, and just slowly die off. If you're worried, just scrape one pane per week.

I just noticed your comment about those eggs in the picture. They are likely snail eggs of some sort, not from the sponges.

The tank will be mainly for zoas and shrooms - basically a small frag tank so it won't matter if there's a short glass barrier in it.

Having said that, I think my wife and I will do a bit of crab fishing tonight anyway. Having no crabs at all will just be better all around I suppose.

Thanks for identifying the eggs as possibly snail eggs. Now that I know what to look for, I won't scrape them off next time I see them.
