I just bought a sleeper gold head goby, its been couple of days now, and it has made up a lot of mess by sifting sand onto my ricordeas, Zoas and other LPS. Should i now be worried or leave it to be. Or should i capture it and just return to my LFS. I have 29g biocube HQI. If I want to capture it will require rearranging my whole aquaescaping. Please need some serious help here. Thanks.
