I have a sand sifting dragon goby that I put in my tank which was a huge mistake because he drops sand all over rare chalices of mine and has killed 2, but I have way too many corals to move lr so needing ideas on how to get him out. I have a diy soda bottle fish trap I have tried but he will not go in I even put sand in the bottle with sinking pellets no luck, needing goby out asap before he does more damage. any thoughts or ideas would be greatly appreciated! thanks in advance!
