When you have a 250.00 discus jump out of a 2 inch gap in your tank glass it tends to cure you about any "aesthetic" issues you have with tightly fitting lids. Crocodile tears, indeed.
I have no problems with tight fitting lids impeding gas exchange for my fish. Or, are you talking about for plants? No, not for low-tech systems. Hi-tech- maybe. But, then, if that is such a problem I would consider not keeping fish because all fish with a swim-bladder have the capability to jump in times of stress, during breeding, chasing between fish...
Its amazing how many people try to convince others on here that their fish ( with swim bladder) do not jump-ever- out of their lidless tanks.
Its more like, "Sure they jump, but I dont mind replacing the jumpers with new fish in order to keep my aesthetics satisfied."
