buy one of those 10 gallon tanks at walmart, just the tank. Then make dividers and divide it up into threesections, 2 2.5 gallon sides, and 1 5 gallon side, and put the 2 men in the 2.5's and put the two gals in the 5 and get two more, or is that to small for 4 females? Or should i just make four 2.5 gallon areas? And would there be any kind of fish that could go in there to clean up after them that wouldnt need aeration, because there bettas are very sloppy and dont eat much, speaking of, forgot to feed the guys for two days, because they moved, is that okay?
