never tried breedin plecs.... they get aggressive at all? cause there in a tank with discus, and the last thing i want is to stress the discus out..... should I get like a couple females for the guy to choose from?? At what age are they ready to breed? where are my exp. bristlenose keepers!
You'll most likely see some fin damage (which heals up) as a pair sorts itself out . . . especially with those fins! I've always keep groups and let pairs form but if you feed well . . . a dominate male will be more territorial over food if it's scarse and if it's been the only pleco in a tank for awhile he's gunna treat anybody (even a hot mama) as an intruder . . . very minimal risk to other fish types. They'll defend an algea wafer but I've never seen one go into hot pursuit mode. If you're introducting a potential mate give her her own chunk of food (cucumber or wafer) so she doesn't have to compete . . . make sure it's at the opposite end from the other bit-o food, good separation and places to hide will be important . . . basically you're acclimating her to him, you'll need a small cave too.
In my exp. breeding pairs are not threatening like chiclids at all, the male defends the eggs and cave until the babies are free swimming(about 2 wks, possibly sooner in a warmer Discus tank) at which point they'll head out looking for algae. I've seen my male chase fish away from right near the cave typically by backing toward the threat fanning its tail vigorously, smart, protect yours eyes. The male will only occasionaly dart out for food, he is a very diligent parent.
Now they can do damage with those sharp pectoral fins so there are no guarrantees but I would be extremely suprised if there was any interaction between the Disc and BN's, they occupy different strata . . don't know what Bn's would do if they came across and egg clutch though . . . hmmm, sunnyside up or scrambled, they (mine) tend towards a strict veggy diet.
Once you get a pair going they'll start breeding like rabbits! I sold an unmated pair to Lilfishie and she had them spawn just a few weeks later. They never paired up in my tank (40g) possibly because I had a dominate spawning pair already. Mine have spawned once amonth.
Re breeding size . . . maybe around 2"???
I was actually concerned for the males health because he was constantly tending a spawn, she never gave him a vacation. . . or maybe he never gave himself one??
Oh, important note, make sure you have some wood in there for them to gnaw on, I've read the ruffage is very important for their diet, I see mine constantly working the wood over . .. down side being the "presto Log" factor, they poop alot.
