Hello all. I have a 55 gallon tank with 2 pearl gouramis, 10 harlequin rasbora, 6 rummynose tetras, and around 8 amano shrimp. I'm looking to add something because it's been the same for quite some time. I was thinking a bolivan ram, but I'm unsure of how it would do with the gouramis ( they're both female if that makes a difference). I've never had rams, so I also don't know if they'd do better in a pair or just a single. Thoughts and ideas appreciated!
