haha jsut got home!! you guys got far!!
yeah right now its 12:16 here
f1shman: i wouldnt try a dragonette unless you get a refugium to grow pods in your tank. I tried one in mine when the tank was newer because i had literaly thousands of pods and each side of the glass!!! Unfortunatly, the mandarin was unhealthy from the fish store and wouldnt eat. she would literaly just sit in a pile of little amphiopods
and you said you didnt know what pods are... soooo.... pods are little crustaceans that come into your tank via live rock or live sand. They are benificial scavengers eating marco-algae or even detrius (food that you feed your fish taht is not eated). There are 3 main branches of "pods" that include but are not limited to isopods, amphiopods, and copepods. They range in sizes too. Copepods are about the size of a pin-head, while amphiopods can be as big as half a centemeter or larger! A refugium will give these pods a safe place to breed free of preditors for your madarin to eat once you/if you get one. Prety much everything in your tank eats them. My clown fish picks them off the glass. my coral banded shrimp picks them out of rock crevaces, and i have a hitchicker pistol shrimp who i believe hutns them. because ive only see half of him and he is very small but i always hear him hunting. They are an overall good thing and a sign of an established ecosystem.
as far as the sand: another thread, someone wanted to get their own florida live rock off of a pier or something, but that was infact illegal. I believe all you need for trapping and taking home livestock form the ocean in florida is a fishing lisence. you are going to want to check your regulations before you try this.
about ordering live rock online: ive always wanted to do it. the only problem is that im worried about the curing process and that i will end up with dead-rock one way or another. However, if you do it in your actual tank before you put any fish or inverts in there, it will cycle your tank and everything would be perfect by the time your tank arrives.
for fish compatibility: i agree fully with what f1shman said, except a bi-colored blennie and a royal gramma might not get along. Both, although classified as peaceful, have been known to be territorial, so if you have 2 docile, rock-hiding, bottom-dwelling fish, you might have some problems with those two.
and for adding base rock: this wold work out fine, but base rock is not as porus as live rock. If you were to look at live rock under a microscope, there are tons of crevices and holes that weaves into the rock. This provides the rock with more surface area and gives bacteria more places to grow and do its thing. This is why the lighter the rock you have by volume, the better.
base rock is made of different materials. It is either lime-rock or lava rock. there arae other types too. Most likely the type of rock in the tanks at your LFS is live rock. But it may be base rock. I know at petcos they have baserock
good night all!! ill talk to you tomorrow morning no doubt!
