New to this site, but hoping someone can help me out here. I have a 95 gallon established tank, over a year old. About 150 lbs of live rock, good 3 inches of sand at the bottom. Sailfish Tang, Clownfish, Yellow Tang, Coral Beauty, 2 Chromis, and a coral banded shrimp. They are all doing very well and are healthy. Water is good, changed regularly. I have been going through Goby's like crazy for the past year. About every other month I'm at the store buying a new Bullet Goby. The most recent one, which died this morning was eatin the food we would feed the fish and was sifting away for a good month and a half but over the past few days was ignoring the algae on the sand and died this morning. Not sure what the problem is. I have tried Diamond Goby's but they werent very good sifters, and the bullets seem to do often. Anyone else have this problem? Any suggestions? I hate flushing $30 down the toilet every two months!
