you have the key right there, as long as the fish are happy, and you like the look of the tank, then it's perfect
i do have a planted tank "or two" around the house. i had about 7 going in my fishroom for a while (as more were being set up), but a slight misjudgment with some pesticide on my wife's part wiped out my shrimp population and the tanks they were in. here's one of my current tanks, a 75 planted. please forgive the pic, it got a massive hack job done to it yesterday:
what you don't see is the stands of ludwigia sp. 'red', pantanal and pogostemon stellatus growing up in the background, here :
i will look for that python in the next few days. it is not heavy at all, i think it costs about $11 to ship a med flat rate box. tubing isn't all that much. but look into it, and let me know.
and come springtime, you're gonna want new plants, we all do when the weather breaks....LOL
show hubby all the vivariums and paludariums out on the web and tell him he can build something like that with a 6 ft tank, that should get his interest......LOL
