Thanks! I'm getting a little frustrated with things right now because my diamond goby decided to jump out of the quarantine tank last night. We taped a good amount of mesh covering to the top of the quarantine tank to keep that from happening, but I guess he found a loose end. Who knows.... Now we are going to try again with a cheaper fish. Everything else does fine, but fish are so difficult! UGH. One day we'll get it right....i hope.. Got a smaller quarantine (10 gallon) that came with a lid, so we're going to give it another try.
