Thanks for the advice guys, I got my head round seriously fish in the end. I actually won a bid on an aqua one ufo 550 in the end, considerably bigger so think my choice is improved.
Definitely getting neon tetras, cichlids ,(soft water kind type) and corydoras is it?
I saw some lovely gold mollies which I would love to have but know they are hard water. I've read that as they have been raised in similar water it doesn't really cause an issue, aware this is opposite to what some of you have advised?
