Tiger and Candy Cane is basically your only two symbiotic ones.
Curly Cue pistols pair with curly cue anemones instead of gobies. All the others are solo for the most part.
There's maybe a couple out there but not really retail, often sold as hitch hikers, but specifying any species that way is pretty difficult and untrust worthy if they use a stock image. WYSIWYG sections can sell already paired rarer species too but actively searching for them might be difficult.
Alpheus formosus (blue leg) might be a 3rd option but I genuinely cannot find photo evidence of them pairing.
Tigers and Candy Cane are both great though. Tigers just get bigger while Candy's are more suitable for nanos or peaceful setups. I wouldn't have a reef without one (but they made sure i wouldn't have a plate coral either :face-with-spiral-eyes:)
