Thank you Mike! >>I am assuming that it is 2 pairs & not more.<< Yes, just one pair each of borellii and Rio Mamore. I will rearrange the plants and hardscaping materials as you recommend. I end up rearranging my plants anyway in that tank, trying to catch all the remaining trifasciata juveniles in it. I will be sure to create a lot of hiding places and screens.
