I have a 4 in. Monster fish or scientifically known as Thalassophryne amazonica for trade in N.W. Ohio. He only eats live shrimp or feeders, not common goldfish. He inhabits a 75 currently with one other Monster fish. He loves to bury himself and hide within the driftwood and substrate. I am looking to trade for a larger or other nature odball fish. I was thinking Larger cats, an aro, or a medium to large bichir. Maybe even something i haven't thought of or listed. Here are some pic's. Thanks for looking!
