Now I have a question about nassarius snails....
My wife said she saw a large bloom of sand pop up on one side of the tank, like a geyser... There is a neat sorta cave created in the sand under a rock over there.
A few hours later I saw it. Suddenly a burst of sand like old faithful pops up about 3-4" near another animal made cave. Is this the snail? I've never seen that before.
Our only fish in the tank are two damsels, the orchid dottyback, a chromis, and our clown pair.
Also, I measured the tank and in theory it comes out to 35g+ (not 30 as I had thought).
This is good to know because I would really like to upgrade down the road to an AIO type tank with sump and ATO for those times that we are traveling.
