Math sir, 2 feet is 24 inches. 30 inches, maybe the max size usually. 72 - 30=42. Even if it was max size in the wild 40 inches, it wouldn't be 2 feet space left. 72 - 40=32. I think before you try to give me advice, work out the answer. And the max size would normally be 30 inches so I'll be fine with a 72 by 30 by 24.
I mean right now, what other requirements do clown knife need in a tank?So what kinda advice are you looking for? Your original question was whether your knives would survive with the bichir since the other one got eaten and our answers were the bigger one, probably, the smaller one, it'll probably get eaten by the bichir or harassed to death by the bigger knife.
