Bristlenose Pleco Ancistrus dolichopterus breeding OR Fish making love

The breeding of Bristlenose Pleco Ancistrus dolichopterus, one male and four females. This group have bred 14 times before. It took 14 days from when they where put in the tank until the eggs hatched. Of the group of four females, only two laid eggs this time. The total number of eggs where 64. Filmed in 2001 with night vision DV camera and infra red light, but recorded on a VHS tape. No need to mention the lousy quality. I hope someone will find it interesting and maybe even useful. A warn
