I am looking for some answers it ideas as to where my fish keep going to. The only 2 things that I feel could be the culprits are either my cortez ray or my bta. So far I have lost are 2 banggais, 2 mollys, a fire fish, a gold headed sleeper goby, a female anthias, and a blue hippo. Out if all of these the only carcasses that have been found are the hippo, one Molly, and the goby. Does anyone have any ideas as to what it could be? My lfs thinks maybe the bta.
