HELP! Brought home a golden head (blue stripe) sleeper goby last night. He got right to workin the sand and even participated in evening feeding grabbing mysis out of the water column. But, this morning he’s MIA and I see no caves/burrows under rockwork; not in the sump; tank is covered. My rockwork should be stable as it was placed on egg crate before adding sand. I’ve got fine (oolite) sand. I was advised by the LFS that the fine sand may be better for it since there’s less chance of it getting stuck in its gills while sifting. Bottom line, should I be worried that I see no evidence of the new fish?
