so almost 2 months ago I gave a new 72 gallon bowfront with stand lids eheim 2075 filter and lights to my sister as there was a breeding group of guppys in a puddle that she wanted to keep. The initial point of the experiment was based on the idea that guppys do not have a negative effect on water quality and they can live in stagnant conditions. So the guppys were back there for the summer, reproduced and then brought inside. The tank is running perfectly, sister at age 12 is maintaining it very well. Guppies have since tripled in numbers.
