Dimensions are 92cm x 41cm x 55cm, but please bear in mind that it is a bow fronted tank. Approximate volume 180 ltr (approx 40 Gallons (UK)).

Yeah, I got a vision 260 and the width at the end of the tank is only 13" compared to 18" or so in the centre, which makes it awkward to have larger fish as they will find it hard to turn at the ends of the tank.
Is the tank 41 cm in the centre of the tank or at the edges? I think it will most likely be the centre so going on that ratio, I'm guessing the edges will be around 11" or so at the ends so the largest cichlid I would put in that tank would be 6"ish (possibly 7) depending on real dimensions.
A blue acara sounds good in that size tank, I'd have another similar sized cichlid as well, some options could be:
Firemouth
Convict
Sajica
Rainbow cichlid
Flyer cichlid
Honduran red point
