Stocking ideas for hard water tank

Yes, I seem to have a wibble in my lists. It's the red dwarf and mosquito rasboras that are ok.
I do apologise and have amended my records accordingly.

The Lido is more of the cuboid type shape, I used to have the 120L version. The 200L is a bit longer. Here's a video of a 200 set up

I think African cichlids would prefer greater length to keep away from each other so a group of small/medium fish that travel vertically through the water column as well as back and forth would probably be preferable.

For smallish shoaling fish that wouldn’t mind the tank length, take a look at Pseudomugil (blue eye) species?
Or for something bigger in smaller numbers, how about a pair of central American cichlids like firemouths? You would need to provide plenty of decor so they could have their own space.

Sorry for the delay in replying. Thanks for everyone's imput.
I was wondering would Rainbow cichlids be suitable for the size tank ?

Rainbow cichlids are a bit big (possibly up to around 7").

So are there any central American cichlids which might be suitable or will they all be to big?

Hi, I was chating to someone the other day and they recomended Barbs. Any thoughts on these ?
The biggest problem I have in my area is a very limited number of fish shops and they all seem set up for the bigger or soft water aquarium.

Some barbs will be ok in harder water, a lot are quite forgiving.
I wouldn't suggest tigers unless you get more than 10, even then they can be proper grumpy....
Pentazona (5 banded) are a bit fussier and do better in soft water.
