You should have gotten some F0-F1's, they look much much better than these rams imo If you can only have 2 fish in a tank like that it's quality that matters
lol my ram (i got him free with a load of other and wasnt setting up a new tank just for him, so thought 'nyah if he gets eaten so be it') was in with fronts, CK, BGK, delhezi poly, 4sen polys, hujeta, venustus and FH....over the years...all were over 6".
he never got touched lol he fights for his space.
