How Can I Get My Bolivian Ram Pair To Breed!?

[jsmeester]

Hey guys. So I have a Bolivian ram pair. They've been a pair for several months. Prolly 5 or more and have not to this day gotten any eggs from them. I really want them to breed too. They are both full grown, the female breeding tube is always sticking out a little bit. I just don't understand why they haven't breed yet for me.
I have several flat places for them to lay eggs and they could dig a whole in the gravel if they wanted to.
The tank mates that are with them are
6 peppered cories
10 guppies(mostly juveniles)
7 glolite tetras
1 male albino bristle nose plecos and 5 1.5 bristlenose plecos that I'm raising out(only 1 will stay (female) once I can tell the sex or guess what it Is.
So it's not like they have to compete for space.
Oh yea I forgot I just added another Bolivian ram(not aure of the sex, which wasn't eating and getting picked on in my 75 gal. He use to live with this pair before I moved him now there back together.
So it there anything I can do to make them want to spawn!?

If you want them to spawn, you may want to get them their own tank. From the looks of your stock, the guppies and cories i know for sure eat eggs, Im certain the glolights will too. I honeslty would not be surprised if they have spawn in the past and you didnt know it because the eggs dissapeared.
