I dont know. It's just sad because he's our favorite fish and the most unique. I have a couple friends with well established 125g reef tanks with 6-8" sand beds and I'm gonna see if one of them can take him. Not sure how I'd put him to sleep... we'd be devastated if we found him dead so I just want to get rid of him. I made some big mistakes since I started the tank including not establishing a deep enough sand bed, and siphoning from the sand bed during water changes (not sucking up the sand just sifting it) which I believe depleted the microbes in the sand that were essential to the health of the goby. When I bought the tank it was recommended by my original LFS
to keep a shallow sand bed and sift it during water changes and to keep the live rock clear of the sand by pointing the powerhead towards the bottom and towards the base of the rock. He said putting the rock on top of the sand would eventually cause the entire tank to die because crud would get trapped Under the rock which would make breeding grounds for bad bacteria, viruses, and parasites. I didn't understand that because I know many people that have had very nice tanks running for years with no big problems. some running upwards of 15 years and they have very deep sand beds with rocks placed on top. It is sad that I trusted this guy but he was an extremely knowledgable aquarist and built very nice custom tanks for years and had some of the most beautiful reef tanks at the store. I believe he gave me some bad info. I've learned that every tank is different and unique. There are so many factors that can make or break a setup no matter how "perfect" it is. It's nature, and I believe the most intricate and complicated part of nature is marine life. There's still so much we don't know. That's what makes reef tanks so rewarding. That's why we do it. Sorry for the rambling lol. Thanks for the help everyone!
