i could throw the sofa out and have a 6ft tanknot sure the kids n hubby would appriciate that though...ive got a tank in the kitchen(25lts) was going to be a betta tank but now houses a rescued goldie!!
and i have the "main" tank in the living room 75L..well its a 80L but only holds 75L after the deco and gravel....![]()
Any of the 'rules' you hear quotes (e.g. one inch per gallon) general take into account decor, substrate etc so even though you have a 80l tank with 75l water it's probably ok to go with '80l' tank in terms of stocking etc.
