You have three females. Middle fish (top picture) is a long-finned variety, which explains the difference in finnage. They’re standard Rams (sold as German Blue Rams but they’re not). No Gold Ram in them either. They’re pale because of the unnaturally (to them) bright substrate. Top fish is in breeding condition. You can tell by the ‘egg tube’ just in front of the anal fin, and the pink belly. If one was male those two would be getting on with breeding and the other would be chased away. If you want a pair I would suggest just keeping one of the three and adding a male. If you keep the one in breeding condition you’ll need to add a male in breeding condition (very colourful), or if you keep one of the others you’ll need to add a male that isn’t yet in breeding condition (not so colourful).You’ll get much better colours out of them on a dark substrate. Light substrates keep the colours somewhat muted.They’re young adults.
