http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=overbreeding#1 I had aquariums in my younger years (heh heh) but haven't for many years...just read a blog in which the writer warned against stocking an aquarium with guppies, neon tetras, mollies and swordtails (for a beginner) due to overbreeding and poor stock leading to inferior fish, short lifespan, etc. Is there anything to this? kiddienurse 2013-08-30
