What Tankmates Could I Have...

[guppy_man]

hi, i have a 39uk gal
it looks a bit bare up top, so i bought 3 vallis, 1 is really tall which i planted by the filter, mainly to hide it lol and the other 2 are at the right hand side of the tank in the corner. And i have some hornwort placed round the tank.
i dont know if you have been reading my tank diary but i have a slate cave starting from 1 end of the tank to the other, with holes throughout, for my bolivian rams
the fish i currently have in the tank are

3 bolivian rams
3 topfin platies (1 died)
1 7" common pleco
1 3" gibbisep pleco
3 1" peppered corys

could there be any other interesting fish i could have in the tank which could make the surace not look sooo boring?

i am not looking for a shoaling fish

thnx

Maybe some Angels, but I think the common pleco will get too big. Some more corys,
