Wow mate you do sound like you've got your hands full and house , we've no room in our tiny two bed terraced house for any more at the min looking to move soon though
we adopted 4 of them as infant crak / heroin addicted babies. We had the room and the need was there. we own a large 6 bedroom 3 full bath 2 story house. I am very looking forward to getten them on there own, selling and buying a nice little 2 bedroom house for me the wife and the fish of course and retiring.
I suppose if you sell your place you could buy you and the Mrs a nice two bed and set each one of the kids up with a little deposit for there own places outta your change (and a nice new fishtank of course )
Fair play mate hahaha ,I bet they appreciate all those BBQ cook ups though my mum was a cook so she always made great homecooked food when I was a kid , I too try to give my kids fresh cooked meals and keep them off the junk as much as possible
After mowing the lawn, did my usual 50% WC on a heavily stocked 125 African Cichlid tank. Realized my wet dry filter was undersized for mechanical filtration to keep up with the messy cichlids. So switched back my old reliable Fluval Fx6. I then proceeded to replace the Fluval 405 with this wet dry filter for my 75 gallon fry/grow out tank.
