New 10G reef tank, added two clown fish. They seem to be doing well (72 hours so far) but spend most of their time in a cave in one rock. They come out to feed but I am wondering if the flow rate is too high for them as they seem to be buffeted around a bit. Rate is set at around 100 G/hour. Is there an ideal rate or is it just they're new and trying to get used to a new environment
