Peaceful Centrepiece Fish

I'm needing 1 more centrepiece fish for my new tank (cycling right now)
Its a 4ft long 48 gallon

These are the fish

1 male dwarf gourami
10 rummynose tetra
10 male guppies
6 albino corydoras

I'm still not 100% on the rummynose tetras and thought maybe to swap them for neon tetras just for the colour but I love how well the rummynose school together.

Only requirements are it needs to be colourful and peaceful enough in this tank. Oh and it can't outgrow it as I only have room for this tank and won't want to have to part with it

I was looking at a bolivian ram but watched a few youtube videos and they didnt seem as colourful as the photos? Whether its photoshop or a certaintyor of light that ahows them off best

Thanks!

 

What about a male sword? The lyretail can be quite large and colorful. Other gouramis may not get along with your DG ... (actually DGs can be..sticky..to stock around as they are sensitive to very active fish as well).

 

Keyhole cichlids

 

Thanks Galathiel. I read swordtails and Mollies could be a bit aggressive? Shame as I saw some really nice ones the other day!
Also that platies were more suitable.....I don't like them as much

Thanks DoubleDutch ill look them up ☺

 

From my limited experience, my swords were aggressive to each other, but haven't really bothered my other species of fish. Personalities of fish can be individual, however, and I can't speak for all of them!

 

Lol thank you. Ill do some more reading

I looked at the keyhole cichlids but not really what I'm after ☺
