Based in the UK, I started keeping marine fish and corals about 24 years ago.
Took a break about 15 years ago due to travel, and then started again about 5 years ago.
I have a 700 litre (sorry, metric!) Display tank with a 500 litre sump and additional frag tank in an outbuilding.
I keep a variety of soft , LPS and SPS corals with 3 clown fish, a sixline wrasse and a Bicolour blenny (I like fish, but don't base my tank around them).
