I've (well, "we've") got 2 big tanks, one 6ft x 2ft x 18" (hubby's community and angel tank), and one 6ft x 2ft x 2ft (mine - severums, festivums and plecs). I've got a 2ft tank waiting to be set up, lord knows what I'm doing with it yet - it was an impulse Ebay buy I'd have more tanks given the chance, but with the two 6fts in our living room, and the shelving holding my land snail collection in my dining room, my rats in our bedroom, and 5 kids and a dog milling about - we're kind of full up
I'm sure I could squeeze a cube in somewhere though....
Thanks every1 for replying. so it appears most have at least 2 tanks, and im thinking of getting a 'smaller' tank for now till i move then upgrade to a bigger tank , but for now will keep to simpleish fish.
