In May I bought a hifin goby right after my aquarium had cycled. A few weeks later he disappeared. I thought he dead. Well last week I saw the ghost fish in the back of my AIO filter spay. I've tried many times to catch him and put him in the main part of the aquarium. He's too fast and has outsmarted me. Everyone I've talked to has said this is a difficult problem. Would a fish trap work ? I know where he is fine. I want him where I can see him. Any advice on how to catch him would be helpful and appreciated.
