Ancistrus? Do they fight or is it prespawning?

[Stan510]

My two Reds in the 240 gallon were entertaining me and the wife as for the first time they were out in the open,on sand and were either pre spawning or two males fighting. One is smaller but with larger bristles. It was a kick to see them go not just round and round- they were also digging out a crater where there was four years of detritus. It lasted for awhile. i was though wondering how I could remove babies one day? I've avoided fish that spawn and protect the young. This could be a problem.

Pictures of the fish so we can sex them?

If they breed, you leave the babies until they are at least 1 inch long and then catch them out with a net
