Hypancistrus, diff kinds in 1 tank

[CanadaPleco]

I am having a 4 foot x 2 foot x 1 foot high tank built up for me. What I am wondering is if I put a bunch of different Hypancistrus species in there will they cross breed (which i dont want). and will they breed at all with the other species in there?

I am thinking it would be a good tank for my L260's and L201's.

Maybe even another one for some large gold nuggets :D but that might just be wishing, they grow sooo slow.

Thanks,

Rich
