I currenlty have a 30 g reef tank with a dwarf fuzzy lionfish and clarki clownfish. The fuzzy has been in there for a while and I recently added the clarki to get some daytime activity in the tank. So far, there have been no problems and the two basically leave eachother alone. The fuzzy has continued normal behavior. I was thinking of adding another fish for more daytime activity. Am I starting to over do it here? Since my tank is small (30 g), I fear there may be an overcrowding issue here. Also, I fear I may not be able to keep up with the waste the three may produce. I do weekly water changes with the best source in town and so far my parameters have been maintained. Is there anyone out there that may be able to provide some advice?? Any suggestions?? I dont want to take too great of a risk here for one more fish. I understand any fish I choose will have to be large enough as not to be eaten by the fuzzy. PLEASE REPLY. I have posted a couple threads and have not got a good number of responses.
