I get what you're saying, however it does matter. You've been able to make a tank work, that's great. I'm happy for you.
However, it didn't work for this person (a large enclosure) and we suggested alternatives to said large enclosure to make the python feel more secure.
I'm glad your python is eating great, that's wonderful. You have success, the OP does not. That's all this is. I agree with whoever told you your tank is too big. I also wonder why you're putting a snake in a fish tank, however that's up to you. We're also not in this thread about you and your set up, but to get the OPs snake eating. Hopefully the new accommodations are successful, as you have been so far.
