Found something on breeding by another guy. As far as breeding goes you want a 29g tank that has no substrate and you want LOTS of hiding caves and spaces, few plants, water with a temperature between 78-84, pH between 6.6-7.2, and a moderate hardness. You should have a powerhead or two in the tank simulating the flow of the rivers in which they are natively found. The flow should be about 8-10 times the volume of the tank per hour. Point the caves so that they are slightly facing the current because the males will use those caves to help raise the fry since the current will oxygenate and clean the eggs. Also, NO TANKMATES! Just the plecos. You will be able to keep a colony of 5-6 in a 29g tank but you need to have lots of hiding spaces and territories. Driftwood should also be added to the tank IMO. Lighting shouldn't matter as long as you try to recreate the photoperiod of the day for them. I'd use the stock lighting that comes with the 29g tank for example 6-8 hours per day. Hope it helped
