are they pairing?

my 2 fire mouths follw each otehr every were and when one gets in a fight the otehr one comes and backs the other up i try and get picso f them but they are camera shy ill try and get some pics but to me this seems like pairing behavoir

well now they are cleanign off this rock quite a bit and fighting off who they can they arent stupid they dont mess with the bigger fish liek the oscar but pretty much every thign else they do here is a crudy pic of them in teh act of cleanign this rock and area
