New Tank For Hard Water

Hi everyone
Have convinced husband to get a tank for home  . Have my eye on a tank 120cm x 30cm 182l, (but might be talked down to 90cm x 30cm). My main prob is my water - about 230 ppm and average 7.4 ph (water company measures). On some sites this is classed as 'hard' but have read a post here saying that it is in fact 'very hard'! I'm not an experienced fishkeeper and would like some advice on what I could put in the tank. Would prefer not to have a single species, and I like fish with personality rather than just looks (starting to sound like a dating website ...)
In my first tank I ended up with guppies (RIP Pinky  ), platies and WCM minnows, so looking for something a bit different from the live bearers.
I know all you fishy fans will have some great ideas - all gratefully received!
Thanks!

Thanks Steve, so "very hard" then!
Having hard water and high PH does seem to limit the choice somewhat - or maybe it's just the fish I like are in the 'pansy' range! My LFS has all types of fish in the "local" water including those that prefer quite soft water. They say that the fish are acclimatised because they were raised in these tanks. Is this right? Surely they can't change their biology that much?

If you want fish with lots of attitude, Rift Lake cichlids, though you would need the larger tank for them. And I would also search for a specialist site as not many, if any, people on here keep them.


I save info that might come in useful, and here is a list I've saved on hard water fish, in addition to Rift Lake cichlids -
most livebearers including the not very common ones (on Seriously Fish, on the knowledge base home page, look at 'Cyprinodontiforms' subdivision 'cyprinodontoid toothcarps'. Sorry about those mouthfuls  )
blind cave tetras
x-ray tetras
lemon tetras
red eye tetras
false penguin tetras
many species of rainbowfish (search Melanotaenia)
some killifish eg Jordanella floridae & Aplocheilichthys macrophthalmus
central American cichlids (though these can get quite big)
and smaller fish such as Danio erythromicron

Thanks ColinB and Sue - knew I would get some ideas from you two!
 
Haven't had time to check them out yet but will do. I like the cichlids but think would be a cichlid only tank - not nec a problem tho.

I don't take caffeine so it will just have to be wine. Perhaps a little later tho'!
Thanks for the link
