Those look great! I like how they have a gullwing kind of lid. I guess that would make checking on them a lot easier, only having to pull half the tub out to open it...

Those definitely up the game on convenience and give at least half again as much floor space as 41q the girls are in.

Unfortunately, I don't have racks that would accomodate those at 6.5 inches. I have 6 and 6 1/4" tubs that do fit tightly. So I'll have to make do with what they have.

In my situation, I could see the possible habitat enrichment in the BMASTERS as an offset to the smaller floor space, but I see an argument for "if it ain't broke, don't fix it".
