So this morning I fed the crew and sat and watched the tank for a bit. After a little while I saw a cloud of smoke come out from between the rocks. I can think of no other way to describe it other than smoke. I grabbed a flash light but couldn't see much. The L201 were in the rocks alone with some very small calvus. Breeding? That would be crazy. Time will tell.
Congrats on your new plecos and good luck! They are very neat. I too have moved up from bushynose and am growing out both Santarem plecos L450 and Mega Clowns L340 with hopes of spawning.
