Jumped out of my tank. Found him this morning. I have 2 screens covering each side of the tank. Tank had center glass brace so I went with 2 frames and brs clear mesh. I think cause I put egg crate squares at each corner to lift metal up off tank rim (wanted to keep aluminum from getting wet) and this made a gap. My kids said he jumped once last week by shooting up and out the gap onto the center brace and then flipped and flopped off onto the floor. They saved him that time. I should have taken blocks out then. But I was like no way it will happen twice. I should have known. Actually thinking about it he once jumped out over center brace and back into the tank while I was standing there. Crazy fish. Needless to say I'm bummed. I lowered the screens do they are tight on the tank top. He was beautiful too over 6 inches and fat. Lesson learned.
