i have two bolivian rams that i got as juveniles that have grown up a bit now.

i left for a 2 day vacation so no lights and no food, when i got back, the two rams that used to fight and stay on opposite ends now swim very closely together.

but strangely they follow eachother around yet still peck at eachother (not violently).

not 100% sure on the sexes but i believe male and female as one is more colourful and has extended tail fin.

is this mating behaviour?
