That is a Bali Red Star. The one that you shouldn't have in a Nano....they are hard to keep. I am hoping that I get lucky. It is very active and moves around a lot. I have been trying to feed it, but it has not eaten from me yet. Everyone thinks that it eats some kind of bacteria off the live rock. Which is why you should have about 100 lbs. for it. But the store in franklin had a lot of them for 13 bucks. At least I will try to save it. I feel sorry for the ones that don't get good homes.
and yes I did add the power head, but I just took it out after a couple of weeks. It helped alot with getting water flow throught the live rock in the back, but I had problems with it falling off into the sand and blowing around everything. I wish that I could find one with very little movement just for rock circulation.
The light is great. I have it on two timers for the Mh and the PCs. The tank runs a little hot but I just keep the ceiling fan running on high. It helps and keeps it around 79-80 during the day and a little lower at night.
Did you get my message about the RBTA on the other board? Does that stand for Rose bubble tip? and if yes....let me know when you have one. I would like one for my two clowns.
