So this morning I woke up, went and took a peek into my tank as I usual do every morning and noticed a small colony of zoas closed up (which are usually open with the moon lights) and something glowing on top of them. I thought well thats a lil odd and upon further inspection I pulled out a nudibranch. This is my first experience with these lil SOB's so what am I in for? Should I pull all the zoas I can from the tank and do some type of dip to make sure the eggs, if there are any, are dead? Im assuming it is a Zoa eating nudi since this is where I found him. I havent really noticed a big change in the zoas I have except some of the colonies which are normally open at night being closed. Im sure this is just the beginning but what can I do to eradicate them.
