I've just ordered a 30x30x16 tall acrylic tank that will become a haddoni specific tank. I'll use some rock, sand, and a lot of water from my 240 cube to start it off. Once ready, I'll try my hand at a small blue, red, and if room, a bright green haddoni (not all at once of course). I've considered adding my 3 year old black occelaris but don't want them getting munched by these anemomes, so I'll probably add my other pair of orange ocellaris, maybe a few more, and see what happens.
I'm thinking a single 250 or 400 watt pendant over the tank would suffice.
I'll push 10 to 15 times turnover through a SCWD for some random flow. I'm going to keep the set up simple, as I still plan on setting up a 72x72x30 or 120x36x30 sometime next summer.
