So a while back I grabbed a BN Pleco for my 30 gallon tank, then I put together a 20 gallon tank and grabbed a BN for that as well. Then i decided I wasnt going to do the 20 gallon and just put the few fish I had into the 30 gallon, including the pleco. A couple weeks later I see little plecos swimming around and now i am estimating there are at least 15-20 plecos in my tank! I haven't taken any special measures for this tank, just filter, bubbler, and 2 small pieces of driftwood. I was amazed, and they continue to breed. Anything special i could do that they would enjoy?
