Hello -- I have a 20 gallon long aquarium with approximately 20 lb live rock and 1 1/2 inches live sand. I have one small percula clownfish, a coral banded shrimp, and a chocolate chip star (newest addition). The tank has been set up for about 10 weeks and is filtered with an Emperor 280 HOB
filter. Current water parameters are: ammonia - 0, nitrite - 0, nitrate - 10, pH - 8.2, temp 78.
I got the star fish about five days ago from Petco. It was drip acclimated to my water over the course of about 3 hours. Over the past few days the starfish has been active most of the time, cruising around the bottom of the tank, the rock, and tank walls, but it seems to return again and again to the surface where it flips one or two legs back along the surface of the water. Is this behavior normal, or is it an indication of a problem with my tank conditions?
Also, can anyone give me advice about the most appropriate diet for a starfish? The clown and the shrimp are currently eating New Life Spectrum Marine pellets.
