I've been through loads of tropical setups, various fish etc but finally really enjoying a mix of lake Malawi ciclids. I've got 17 malawi's, 2 cat fish and a bristle nose plec. You can get some really stunning looking malawi's, I went for them because the colours seem closer to marine compared to most tropicals. I made the mistake of not having enough at first, they'd fight badly and kill each other off. Since having 10+ they've been great.

I'm really wanting a marine setup at the moment and funnily enough was almost about to buy something a couple of days ago. Trouble is two tanks in the lounge is a bit much.
