thanks carol, sounds like a good read, back to the oscars, when i first got my tank, did some asking round wanting to know what would be good fish to put in my tank, as its big i didn't want to waste the space & i was told oscars were great to own but the glass thickness need to be xxxx thick ( cant rember) & i measured mine & its only 6mm on 2 sides & 5mm on the other 3, (sound dodgy???) talked to the lady in the fish shop & she said glass on came in 2 thicknesses & i tried saying to her mine where neither of them, didnt end up getting very far with her, ( funny thing is the tank came from that shop!! even tho it was a few years ago) so between thinking my glass is too thin & not being able to buy baby oscars that was that, can anyone shed some light on the glass thickness thing, does it need to be thicker than what i have for oscars or is it a pile of rubbish?
